Crashing when switching screen resolution

[molohov]

Hey there,

I have a bug that I can recreate with a few steps. First, a bit about my configuration:
Windows 7 x64 SP1
More than enough power to run Dexpot
3 virtual desktops: 2x 1920x1080, 1 at 1280x720.
I use the Taskbar Pager.

ISSUE: Dexpot crashes when switching desktops set at different screen resolutions.

CAUSE:
Switching between any number of desktops at the default resolution of 1920x1080 is fine. However, switching from a 1920x1080 desktop to the 1280x720 desktop the Taskbar Pager disappears, and Dexpot crashes. Attempting to open the the settings via the tray icon results in a frozen Dexpot that must be killed manually. The Pager also doesn't respond.

In order to recover my opened windows on other desktops, I kill Dexpot in the task manager and restart it. However, once it's restarted, the Taskbar Pager doesn't load and the settings window is frozen like before.

STEPS TAKEN:
I've reinstalled Dexpot many times, using Revo Uninstaller to remove any traces that the program might leave, but I can always recreate the issue.

I can submit a log file if requested.

Many thanks for any help!

So far we haven't been able to reproduce the issue on any test system.

How can you tell that Dexpot crashes? Is there an error message? Does the problem also occur when the Taskbar Pager plugin is not enabled?

I can submit a log file if requested.

Please do. You can send it to me via email.

Did you read my answer above?

I have more or less the same problem.
My setup is:
Asus Eee 1005 PE (Intel atom N450 1.66 GHz),
Intel GMA 3150 with driver version 8.14.10.2230 (from 2010-10-24),
2 GB ram and a 8 GB SD in Readyboot,
running Win 7 Starter 32 bit SP1.
Latest version of Dexpot (1.5.8 build 1434).
Native rez of screen is 1024x600

I have three desktops in DP (Dexpot). When I set #3 to 1024x768 rez things go bad. DP suddenly claims that I am in #1 (in tray icon pic, rightclick on tray icon and dialogs). I can no longer switch to another desktop.
I kill DP via PE (Process Explorer), reset rez manually and restart DP, which then gives me desktop #1. I then switch to desktop #3 and rex changes, DP claims I am in #1 and I can no longer switch desktops. When I call up the "configure desktop"-dialog it hangs. This is the point where I made the dump via Process Explorer on Dexpot.

For curiosity I tried a workaround. With Dexpot restarted and all rez's set to native, I switched to desktop #3, and then via the win system dialogs set the rez to 1024x768. The problems appeared a little bit different this time. Rez change went ok. So I rightclicked tray icon and tried to switch desktop to #2. Immediatly rez switched to native 1024x600, but DP tray icon showed desktop still as #3. When I rightclicked the tray icon nothing happens. When double leftclick on tray icon another bug appeared.
Screen blanked totally (I had Icons on #1 and #3 but not on #2) and left 2/3 of screen goes black while right 1/3 keeps background colour. A frame is seen at the edges of screen, maybe a maximized window? When double left click anywhere (mouse pointer is not visible) win 7 program crash standard dialog for DP appears. I chose stop prog and is at desktop again with background colour of desktop #3.
Restarts DP and all is normal, all desktops are restored and desktop #3 has native rez both in settings dialog and when visited.

Through all of this, when DP is killed and restarted, all open windows on all desktops is always restored faithfully (which really made this post easier to write ) which I think is very good. A program that crashes and not messes up what you're working with is a well designed program.

I searched the c: for dexpot.log and it sadly just isn't there. I double checked that the logging box was checked. Process Explorer let me make two dumps of Dexpot, one mini (897 kB) and one full (65.6 MB). I should say that I have no idea whatsoever if those dumpfiles is of any use since I don't know how PE creates them, when I tried to open the mini dump with TED Notepad it is a binary file. Also, when I made the dumpfile Dexpot was switched to Swedish, I don't know if that matters though.
If there is any way that I can help more with this pls let me know.

Dexpot is essential for me and if this bug can be solved swear I will donate.

Thanks, Barbafant

Please copy the attached file to your Dexpot installation folder and test if the problem still occurs with this version.

Thanks for a very fast answer!

I have tried it and it seems to work perfectly!! I'm switchintg happily back and forth as I am writing this. Obviously I've only tried it for a couple of minutes, but the bug was easy to reproduce from the begginning and therefore it should be equally as easy to see that the fix works.

Impressive support! And as I promised, I'm donating.

Hi Patrick,

Sorry for the ridiculously late reply. I got caught up in my exams and didn't have time to come back and check for replies.

I downloaded your new version and am happy to say that it works now! I'm very happy! Out of curiousity, do you know what the issue was? We didn't submit any error logs to you, so you must have recreated it somehow?

Many thanks again. I will consider a donation when I start my internship

The second person having the problem, ivohaag, sent in a log file.

I was having the same issue when going from the terminal to an RDP connection. This seems to have worked even though it's not the latest version and the software bugs me to update.
Thank you!
