I'm glad that it's working now, I'm closing the issue. If it comes back or if you find a way to reproduce it, leave a reply and I'll reopen it.

Regarding grouping vs. combining, you can find the answer in the help file:

I can't reproduce the problem. Does it happen when the tweaker is not running? If not, does the issue happen when all of the tweaker options are off? If not, can you find the option that causes the issue?

You can try using Process Monitor as suggested here:

I haven't tried doing that myself, but perhaps it will help.

Also, there might be a chance of your antivirus interfering with the tweaker. Many times, where there were no other explanation, the antivirus was responsible for various issues. You can try adding the tweaker to the exclusions list and see if that makes any change.

I'm not familiar with such a bug. You can verify that the startup is not disabled in Task Manager. Other than that, it should just work, and if it doesn't then I believe that there's something wrong with your system.

Does the issue happen when 7+ Taskbar Tweaker is not running? Since the issue doesn't happen on the taskbar, it's possible that it's not related to the tweaker.

If it happens only when the tweaker is running, can you check whether it happens when all of the tweaker's options are off? If no, please find the option that causes the issue.

Please make sure that you're using the latest version of the tweaker, v5.11.3.

You can achieve this with the advanced options. Refer to the help file for more information.
