Studio’s built-in edit tools, as well as SBS and F3X are having an issue where the selection handle is prioritizing any parts before the actual selection. This makes me grab the part instead of doing the action. See the video I linked for more:
As you can see in the video, I can still use the handles sometimes but only if the part around/under it is locked.
This started happening yesterday. I use SystemMenu studio so I switched to RibbonBar and still have the issue.
Edit: Locking thread, another thread with a similar issue is already made.
