On df 11.b2 on win10, taskbars would suddenly stop responding. Only fix is to quit DF and restart DF (couldn't find a way to ask DF to just restart the multi-monitor taskbar component).

I have the same issue, the other way to fix when this happens is to disable and then re-enable multi-monitor taskbar via the right click menu on the status tray icon. Unfortunately, since you have to right click and navigate the menu twice (disabling the taskbar closes the system tray menu), it's almost faster to just close and restart DisplayFusion instead.

I still see the same issue after updating to Beta 3, where the taskbar will lock up until I close/reopen DisplayFusion or Disable/Enable the multi-window taskbar. I'll see if I can grab logs the next time it happens.

Same issue with locking. I have been experiencing for last 2 months, including beta 2 and agin today on beta 3. I created a powershell script to kill and restart display fusion.
