Desktop Full-screen preview and window catalog has stopped working. A problem has caused the program to stop working correctly. Windows will close the program and notify you when a solution is available.

What's the error message?

OK, this is fixed now. Thank you! But the full-screen preview crashes not showing anything. I.e. when I try full-screen preview, I get only an error message (althout Dexpot keeps working). What should I look into?

Thank you.

Check "Assign applications". Sounds like you have something assigned to Desktop 8 with the "Swicth to desktop" option set to "when activated".

The desktop you're currently on is always shown in bold.

Was working fine with 9 desktops, but suddenly...
1. Every desktop I go to (by any means - shortcut, manager etc.) - for the first 1 second I see the right Desktop, and then - Desktop 8!
2. From the full-screen preview grid I can click to any desktop, but any further action (such as right click) immediately throws me to Desktop 8.
3. In the Configure Desktops menu Desktop 8 is BOLDED! (strange, right?!)
4. The drop-down menu under "This PC" in the Explorer sidebar has "Desktop 8", instead of "Desktop" for some reason!! Although all 9 "desktops" folders are actually in the user folder.
What the hell is that weird stuff and what can be done?
Thank you!
