I have experienced this issue two times in the previous week. I'm running Windows 7 64-bit, DF8 Beta 6, and likely had Chrome, Firefox, VLC, and Black Desert (game that runs in full screen windowed mode) running both times. What happens is I will click a window on the taskbar, and the taskbar instantly freezes up. Click again and Windows says that DisplayFusion.exe isn't responding, so I end the task. When I run DisplayFusion again, it becomes very buggy. Alt + Tab wasn't working all the time, but Alt + Esc would. The taskbar would eventually freeze up again, and need to be restarted, which I did a few times. After doing a reboot, everything was back to normal.

Here is the log that begins before starting DisplayFusion after one of its crashes.

Here ya go

Well it didn't happen for a few days, even without disabling application hooks. Then, the day it did happen, I had level 2 logging enabled for one of the times, so I've attached that (CrashL2.log).

Another issue I've had only a few times is where the alt + tab window doesn't show up, and it doesn't switch between windows either. Pressing alt + esc works when this happens. Restarting the program fixes it fortunately. If you wanna look into it, I also attached a L2 and L3 log in which I started logging, pressed alt + tab once, and copied the file.

Here's the L3 log for the alt + tab bug. Same settings as the previous post a few days ago.

Appreciate it...I have been keeping up to date with the betas, and actually forgot about the issue entirely. It must have been fixed in beta 9 or 10! Thanks
