What is your version of explorer.exe?
Are you using ExplorerPatcher, StartAllBack, or something else? Which version?

Answer
From version 3.8, StartAllBack uses its own taskbar, so 7+ Taskbar Tweaker doesn't work with it.
Currently, you can either stop using StartAllBack, stop using 7+ Taskbar Tweaker, or stick to an older version of StartAllBack before 3.8.
