That's not a bug, that's how it works, with or without the tweaker. Changing from bug to idea.

If the issue persists after uninstalling the tweaker, the tweaker has nothing to do with the issue.

7+ Taskbar Tweaker doesn't do permanent changes to the system.

The option is not supported in Windows 10.

It's not about the builds being stable in the sense of having, or not having, problems.

The tweaker (mis)uses the internal representations of variables and structures in explorer. These representations usually don't change between stable versions, but they change often in experimental builds. Thus, if I decide to support the insider builds, there would have to be a different tweaker version for every build.

Fast Ring builds are not supported. More information:

OK, I figured that you were probably using the beta version, and I could reproduce the issue. I've released a new beta version which should fix it.
