Issue:
The Alt + Tab keys stop working intermittently - I press these keys and nothing happens at all.
This issue started after upgrading to Beta 19 from the previous Beta.

Version:
DisplayFusion Pro v10.0 Beta 19
Windows 10 (1803) (17134)

Workaround:
To make it work again, it is enough to:
1) Open "DisplayFusion Settings"
2) From the left, click the Alt+Tab page
3) At the bottom click "Apply" and "OK"

Attachements:
1) DisplayFusionDebugInfo.zip
Clicked the "Troubleshooting" page > "Export Info to File"
2) DisplayFusion Backup (2023-Jan-23, v9.9.99.119-BETA, SERGEIS-7490).reg
Clicked the "Options" page > "Export Settings"

I enabled the debug.
When I encounter this issue again, I will attach the Debug Log.
Thanks.

The issue occurred again on 30 Jan 2023 between 21:20 and 21:28 GMT+02:00

Attached files:
(1)
DisplayFusion_Debug_Info.zip
Export from the Troubleshooting tab
(just before the export, I changed the level to "ALL" > clicked OK, and as before, ALT+TAB started working again immediately)
(2)
DisplayFusion_Settings_Backup.reg
Export from the Options tab

Thanks

I did NOT have this issue in v9.9
This issue started after upgrading to v10 Beta 19 from the previous Beta.

I've got the same issue on Beta 19. Rolling back to Beta 18 right now...will send more info tomorrow wether it stopped or not.

Also an additional info:
Closing (exiting) DisplayFusion and reopening it "fixes" the issue temporarily.

Status update - rolled back to Beta 18 more than a week ago - this issue did not occur

Status Update - this issue does not occur in Beta 21

Status Update - just experienced this issue in Beta 22

I am using Windows 11 and Displayfusion Beta 22, and face the same problem. Occasionally, the alt+tab function of Displayfusion has no respond (seems like only the alt+tab function is crashed). This can happen anytime, maybe after using DF for a few days or just 1 minute.
When this happens, both the Displayfusion and the Windows default alt+tab function are disabled. The only way to fix it is to re-apply Displayfusion settings (no change to setting is required).
I was using Windows 10 in January (forget which version) and didn't face this problem at all. I am not sure whether there are incompatibility issue with default alt+tab function in Windows 11.

It's not easy to reproduce this bug but for your information:
I am using 2 monitors.
Manually moving windows (e.g. Excel, chrome) from 1 monitor to another MAY cause this bug.

I have just successfully reproduced this bug by:
manually moving a Microsoft Excel window from one monitor to another, and keep moving it back and forth between the 2 monitors.
I did NOT use another function key to move the Window, I moved it manually with my mouse.
