That happens because the latest version of the tweaker reserves some memory for troubleshooting purposes, in an attempt to solve this issue. Note that the memory is only reserved, and not actually used until it's needed.
The commit size will be restored in the next version, if the issue above is indeed fixed.

The issue could have been fixed in v4.5.10, but I can't tell for sure, as it's not easy to reproduce.

I could reproduce the issue. I'll see what can be done.

Thank you for the report. That was indeed an oversight, and should be fixed now.

Please provide more details. What doesn't work?

Implemented as an advanced option, disable_items_drag, in v4.5.10.

Automatic updates are available in v4.5.10.

Fixed in v4.5.10.

Try the disable_items_drag advanced option in 7+ Taskbar Tweaker v4.5.8.12 beta.
