Basically same issue as the raid manager issue someone else posted. Item is selected to be managed/hidden in MoveAny, but it remains on screen. It can be moved without issue, but hiding it is impossible. This has only been an issue for the last couple weeks or so (Blizz maybe protected it?).

This is the Dragon Isles/Khaz Algar Summary minimap button, just for reference.

Didn't seem to fix it. Still persists after update. Marked as Hide, does not Hide.

v1.7.60

works for me on retail wow, does it work for you when only moveany is enabled?
