That's a strange one! I haven't been able to reproduce this here. Is there anything specific that seems to trigger it on your machines?

Ok, I haven't run into this at all during regular use or testing, but I'll keep an eye out for it. If you find a consistent set of steps that will reproduce it, please let me know.

Could you guys attach a backup of your settings? (Settings > Options > Export)

Thanks!

Thanks! Could you attach a copy of the DisplayFusion troubleshooting info when you can reproduce this again as well?

• Open the Settings > Troubleshooting tab
• Click the "Export Info to File" button
• Reply with the file attached

Thanks! Do you remember which app was still on the Windows taskbar when you captured that info? The info indicates that DF thinks X1 and Spotify were removed from the Windows taskbar.

Thanks! We're pretty sure we know what's causing this and we have a potential fix for Beta 23. We'll let you know when it's available to try, and if it still happens with Beta 23, we'll get you to send a debug log as we've added some more logging as well.

Hopefully within the next couple of days

@Fred: We've just released 10.0 Beta 23. Could you give it a try and let us know how it goes?

Would you be able to capture an L2 debug log for this issue?

• On the DisplayFusion Settings > Troubleshooting tab, change the Logging drop-down to "L2: Log Detailed" and click Apply
• 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

Thanks!

Thanks! I can see in the log where DisplayFusion is attempting to remove it from the Windows taskbar. There aren't any failures in the log, but I believe Windows doesn't return anything for that API call

When this happens, if you kill explorer.exe with Task Manager and start it again, does that also fix it?

Does just restarting explorer.exe fix it? (Without restarting Windows itself)

Ok, thanks! How long does it take before the issue occurs again? Just wondering for a test machine here how long I need to leave it logged in for.

Thanks!

Interesting, might be a tough one to reproduce here but I'll keep an eye on it!

Thanks! We'll take another look at the troubleshooting info and logs.

I suspect what's happening is that something is breaking in explorer.exe, then when DF asks it to remove the button from the taskbar, it fails to do so, but doesn't tell DF that it failed. We need to look into a way to confirm that though.

We'll keep you posted!

We've just released 10.1.2 Beta 1, and we've added some more logging to help track this down. Could you enable debug logging and send over a new log next time you notice the issue?

Thanks!

Could you enable L1 debug logging and send me a copy of the log next time it happens?

Thanks!

@Kirk: Could you send over a debug log for this when the taskbars are missing?

• On the DisplayFusion Settings > Troubleshooting tab, change the Logging drop-down to "L1: Log Minimal" and click Apply
• 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

Thanks Fred! We've got an idea of what's causing this now, just need to figure out the best way to solve it. We'll post an update when we've gotten it sorted out.

We've just posted DF 11 Beta 3, and this should hopefully be all fixed up now.

Thanks!
