Starting up DisplayFusion again starts the issue again.
Upgraded to 26200.8039 and the problem still persists. ]]> https://www.displayfusion.com/Discussions/View/start-button-suddenly-stopped-working/?ID=019c4d02-1eba-75ff-839e-95e3820b6f61#14 Fri, 27 Mar 2026 13:53:31 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/start-button-suddenly-stopped-working/?ID=019c4d02-1eba-75ff-839e-95e3820b6f61#14 DisplayFusion I actually had this happen on a different machine that doesn't have DisplayFusion installed, after updating to 25H2 26200.8037.

I have used vivetool to disable the latest windows start menu and it appears to resolve the issue for now.

I've attached a screenshot of my Start Menu settings. I didn't actually enable it manually — it was automatically applied after a Windows update. I'm currently on Windows 11 version 25H2, build 26200.7840.
Thanks for looking into this, I really appreciate the support! ]]> https://www.displayfusion.com/Discussions/View/start-button-suddenly-stopped-working/?ID=019c4d02-1eba-75ff-839e-95e3820b6f61#5 Mon, 23 Feb 2026 16:06:20 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/start-button-suddenly-stopped-working/?ID=019c4d02-1eba-75ff-839e-95e3820b6f61#5 DisplayFusion Could you send me the steps you used to enable Categories for your start menu? ]]> https://www.displayfusion.com/Discussions/View/start-button-suddenly-stopped-working/?ID=019c4d02-1eba-75ff-839e-95e3820b6f61#4 Fri, 20 Feb 2026 22:49:19 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/start-button-suddenly-stopped-working/?ID=019c4d02-1eba-75ff-839e-95e3820b6f61#4 DisplayFusion Hi, I analyzed the log with the help of Claude AI and found something relevant. When clicking the Start button on the DF taskbar, the process fails with:
FAIL: windowHandleStartMenu is NULL. [System.Exception]
This happens twice during reproduction. DisplayFusion detects the Start Menu opening but can't grab the window handle in time, so it silently aborts.
The move mechanism itself works fine — pressing the Windows key opens the menu on the primary monitor and DF successfully moves it to the active one. The issue seems isolated to the direct taskbar button click.
My guess is the new categorized Start Menu changed the timing of when the window becomes available. Hope this helps the devs pinpoint the issue! ]]> https://www.displayfusion.com/Discussions/View/start-button-suddenly-stopped-working/?ID=019c4d02-1eba-75ff-839e-95e3820b6f61#3 Fri, 20 Feb 2026 22:43:12 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/start-button-suddenly-stopped-working/?ID=019c4d02-1eba-75ff-839e-95e3820b6f61#3 DisplayFusion Hi, I'm not the OP but I'm experiencing the same issue. When I click the Start button on the DisplayFusion taskbar, nothing happens at all.
This started happening after I updated the Start Menu to use categories. Here's what I've noticed: if I'm focused on a window on another monitor and press the Windows key, the Start Menu opens just fine. But if I click the Start button directly on the DisplayFusion taskbar, nothing happens. The primary monitor's taskbar works perfectly when clicking the button — the issue is only with the DisplayFusion taskbar.
I have a 3-monitor setup. I went through the troubleshooting steps and attached the zip file below. I reproduced the issue at around 10:35 PM UTC (7:35 PM Brasília time).
Any help would be greatly appreciated, thanks! ]]> https://www.displayfusion.com/Discussions/View/start-button-suddenly-stopped-working/?ID=019c4d02-1eba-75ff-839e-95e3820b6f61#2 Wed, 11 Feb 2026 18:07:05 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/start-button-suddenly-stopped-working/?ID=019c4d02-1eba-75ff-839e-95e3820b6f61#2 DisplayFusion Could you send me a fresh debug log? Here are the steps:

• On the DisplayFusion Settings > Troubleshooting tab, change the Logging drop-down to "L1: Log Minimal" and then click "Clear Log"
• Reproduce the issue and note the time so we'll know where to check in the log file
• Click the "Export Info to File" button on the Settings > Troubleshooting tab
• Reply with the file attached
• Disable debug logging after sending the log

The start button on my DF taskbars do not work with a mouse click.
