Zugg Software :: View topic - [Fixed?][3.10a] AV for duplicated mapper window after conversion from 3.08

Novice Joined: 01 Dec 2007 Posts: 49

I think the bug I posted as a Search bug is actually this, and search is playing havoc with focusing the window/mapper?

Here's a pic of the "maps" i'm using.. Note: I'm not utilising the the mapper at all at this point. Don't have a map object in my setting either. Nor do I open the Mapper window in play.

Hope it helps..

First, go into the Settings Editor and delete any extra Map objects. Now exit CMUD and restart CMUD and then hold down the SHIFT Key when clicking the Open Offline option. This will recreate your layout file and will get rid of all of the hidden docked mapper windows that you showed in your screenshot above.

Now keep an eye on your Settings Editor and if you find a procedure for creating a duplicate map object, or if you find a procedure to create a duplicate map window in the Window menu, then post the procedure.

But once you get lots of windows like that, CMUD is going to save them in your layout. Your Window menu screenshot is showing that you have lots of hidden mapper windows within your layout, and those won't go away until you reset the layout as I described. Then we can focus on how to reproduce the problem that led to this condition.

I know about magical SHIFT key, but thought using it instead of bug reporting will be not fair for those who will upgrade theirs 2.XX sessions to 3.XX.

Ok, holding Shift key made things worse. Now I have 2 hidden "MySession Map" windows (each has the same map loaded) and visible mapper window with "Mapper" caption. Not "Automapper", but "Mapper". Same thing in the Window menu - "Mapper" If I bring up these 2 hidden mapper windows, they works normally, although I did not create them. And the empty "Mapper" window is the thing that makes AV errors, exactly the same I post in the beginning of this topic.

N.B. I have only 1 Map object.

Additionally, I've deleted layout file and ran CMUD. Now, there was only 1 hidden mapper window "Mapper". I selected it from the Window menu and load my map through the "File\Open..." menu. My map has been loaded normally. Then, I've saved my layout and restarted CMUD. On session startup I saw "Loading map" (or whatever) progress bar, but after session has been loaded I see empty "Mapper" window again. My map was loaded to another mapper window (hidden). And visible empty "Mapper" window produces the same AVs again.
Summarizing on that, CMUD sees that it must load a map on startup, but it fails to see existing mapper window. This results in creation of a hidden mapper window.

Hmm, this simple procedure reproduces the problem for me:
1) Run CMUD, create a new session, save it, open offline
2) From the "Window" menu select "Mapper"
3) From the Mapper menu select "File\Open..." and open any map file you have
4) Save layout
5) Restart CMUD, open your test session offline

You Mapper window will be visible, but empty. Click on its menu to get the "Access violation at address 00CF1AED in module 'cMUD.exe'. Read of address 00000194." error. There is hidden mapper window with loaded map as well, which is works normally.

Following your steps Zugg (delete and reset layout) and the multiple mapper options are gone from the menu.

I'm not sure if it's meant to be a sideeffect or not, but there is no longer any option at all relating to MAPs in the Window menu.

I tried this with one of my old maps and it worked just fine.

After additional tests I can say that there is a difference between a mapper called by "Window\Mapper" menu and a mapper called by "Map" button from the main CMUD toolbar. Or, which is more probable, calling mapper from the menu does not init all variables required which results later in various AVs; mapper called by "Window\Mapper" menu can't draw\save\load maps, it only can draw mapper window itself.

Compare results from these 2 procedures

1a) Run CMUD, create a new session, save it, open offline.
2a) Click on the "Map" button from the main CMUD toolbar.
Mapper correctly creates default map for current session.
3a) From the mapper menu select "File->Save As" and save the map under different name
Mapper successfully saves the map.
4a) Exit CMUD.

1b) Run CMUD, create a new session, save it, open offline.
2b) From the CMUD main menu select "Window->Mapper".
Mapper doesn't create default map for current session.
3b) From the mapper menu select "File->Save As" and save the map under different name
Mapper crashes.

As I understand, "Window->Mapper" menu was designed for letting people open additional mapper windows. The problem for me is that by default, when CMUD loads a real session, it opens a mapper with the latter procedure, leaving me with no opened map and with ready-to-crash mapper window.

I think I see why I couldn't re-create this problem. One of us must have a messed up installation.

Using the procedure you described in the second step, I don't have a 'Mapper' under 'Window' when I first open my new session offline. As a result I don't get the subsequent errors that occur.

When Zugg finishes his birthday celebrations, he can weigh and say which is correct. I'll try a new install on my home machine this evening to see what happens.

From what Zugg said last week, I think that the Mapper is only supposed to appear under Window when you already have a mapper window associated with the session.

A small update on this thread.

Tech was right: it was not a clean install. I just uninstalled 3.08 and then ran setup for 3.10a.

The cause of the problem was my old default.xly, which had a reference to a Mapper window. This mapper plus a mapper from the session layout file gave 2 mapper windows and that was the first symptom I saw after 3.10a installation. I do not know why default mapper stays active after I have a session loaded...
I renamed existing default.xly and let CMUD recreate it - now there is only 1 Mapper window and everything works fine. (Note that running CMUD without default.xly file results in opening simultaneously of the "Sessions" window along with untitled session with status window. That untitled session has 2 untitled packages in it. Dunno is it a bug or no. I closed that untitled session and saved new default layout).

The question is, how can I reset default layout, not the session layout without need to delete a file? Can CMUD overwrite existing default.xly file on install? I think there is no need to keep it.

Here is a part of my old default.xly file (was created in April)

Just delete the old default.xly file to restore the default layout.
