Sorry for the delayed response - I never got a notification that there was a reply to my post.
I am currently using Windows 11 Pro, version 23H2, OS build 22631.4169, and I am using Groupy 2.15.
I am only unzipping files by right-clicking and choosing "Extract All..." from the Windows 11 context menu - no third party extraction tools.
Not sure what the preferred method of sending a video is as there doesn't appear to be an option to attach anything but a photo to a post, but here is a link to a screen recording stored my google drive:
Screen recording on Google Drive
If you watch the screen recording, you will see than when I extract the file, the whole group of windows resizes to the extraction dialogue box's size. Then, it appears that the group reverts back to the original size once the extraction is complete, but clicking on a different groupy tab makes the whole group small again. It's really annoying to have to keep resizing my windows...
