I cannot reproduce that. Does it happen with a specific window/program, or with any program?

Can you provide your exact OS version, tweaker version, and if possible, a video that demonstrates the issue?

I couldn't reproduce it on my PC, Windows 10.

Please provide more details:

• Your OS version, including build number and bitness.
• Your 7+ Taskbar Tweaker version.
• If possible, a video that demonstrates the issue.

Probably won't be implemented in the tweaker, but you might want to try out T-Clock.

Which application has this issue?

Perhaps that's a duplicate of:

I'm not sure about Classic Shell (you can ask its author) or the trackball, but 7+ Taskbar Tweaker shouldn't affect Aero Shake in any way. It works as expected for me on Windows 10, and I use 7+ Taskbar Tweaker with many options.

Looks like this is what you're looking for:

Do you have a way to reproduce the issue?

Also, please check whether the issue exists with older versions of 7+ Taskbar Tweaker.
