Are you getting the error message with the same code, 206?

Are you using the latest tweaker version?

Are you using an insider build of Windows 10?

Office apps in general, and Word in particular, have a number of non-standard user experience behavior. Here's another example. I don't plan to work around these issues with the tweaker.

I'm glad that it works now.

You can use emptyspace|ldblclick, it shouldn't cause conflicts.

That's what I have on my computer as well, and it works. The only thing I can think of is perhaps that you enabled compatibility options for the tweaker - this can cause issues. If that's not the case, maybe some intrusive program such as an antivirus conflicts with the tweaker.
Does explorer restart when you get the error? If so, it crashes - can you provide a crash report?


How do I find event logs when a program crashes?

The issue here is that the BSOD doesn't stop after uninstalling 7TT =(

In such case, I doubt that it has anything to do with 7+ Taskbar Tweaker.

I'm using the same version, and it works for me.

Can you go to C:\Windows, right click on explorer.exe, choose Properties -> Details, and post the file version?

Which version are you using? The tweaker supports the latest version, Windows 10 Fall Creators Update.

Note that insider builds are not supported by the tweaker.
