Is it still an issue?

I'm not sure I understand what the issue is, and it's quite old, so I'll close it.
If it's still an issue, making a video that demonstrates it will help.

Fixed in v4.5.10, except for the cases when the folder window runs in a separate process.

Closed due to a lack of feedback. If there are still issues, please leave a reply or create a new topic.

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?
