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. ]]> RE: DisplayFusion Pro v10.0 Beta 19 - the Alt + Tab keys stop working intermittently https://www.displayfusion.com/Discussions/View/displayfusion-pro-v100-beta-19-the-alt-tab-keys-stop-working-intermittently/?ID=1dca09e1-a538-4664-bd14-4101ea49d134#14 Mon, 20 Mar 2023 17:29:04 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/displayfusion-pro-v100-beta-19-the-alt-tab-keys-stop-working-intermittently/?ID=1dca09e1-a538-4664-bd14-4101ea49d134#14 DisplayFusion 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. ]]> RE: DisplayFusion Pro v10.0 Beta 19 - the Alt + Tab keys stop working intermittently https://www.displayfusion.com/Discussions/View/displayfusion-pro-v100-beta-19-the-alt-tab-keys-stop-working-intermittently/?ID=1dca09e1-a538-4664-bd14-4101ea49d134#13 Thu, 16 Mar 2023 11:06:24 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/displayfusion-pro-v100-beta-19-the-alt-tab-keys-stop-working-intermittently/?ID=1dca09e1-a538-4664-bd14-4101ea49d134#13 DisplayFusion Status Update - just experienced this issue in Beta 22 ]]> RE: DisplayFusion Pro v10.0 Beta 19 - the Alt + Tab keys stop working intermittently https://www.displayfusion.com/Discussions/View/displayfusion-pro-v100-beta-19-the-alt-tab-keys-stop-working-intermittently/?ID=1dca09e1-a538-4664-bd14-4101ea49d134#12 Fri, 10 Mar 2023 16:35:07 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/displayfusion-pro-v100-beta-19-the-alt-tab-keys-stop-working-intermittently/?ID=1dca09e1-a538-4664-bd14-4101ea49d134#12 DisplayFusion Status Update - this issue does not occur in Beta 21 ]]> RE: DisplayFusion Pro v10.0 Beta 19 - the Alt + Tab keys stop working intermittently https://www.displayfusion.com/Discussions/View/displayfusion-pro-v100-beta-19-the-alt-tab-keys-stop-working-intermittently/?ID=1dca09e1-a538-4664-bd14-4101ea49d134#11 Wed, 22 Feb 2023 21:45:42 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/displayfusion-pro-v100-beta-19-the-alt-tab-keys-stop-working-intermittently/?ID=1dca09e1-a538-4664-bd14-4101ea49d134#11 DisplayFusion I can't reproduce this issue here on Beta 21.

Ah, so it was working fine in Beta 18? Can you roll back and confirm that the issue goes away? Here's the download link: https://www.binaryfortress.com/Data/Download/?DownloadID=c647cf98-737b-42ba-8cd9-0e2f87343455&Log=0
