I was in the Finder trying to drag files around in this unresponsive network drive and all the sudden I end up with folder and question mark icons across the top of all my finder windows like this:
Those question marks used to be folders but I was trying to delete the folders and it didn't remove the unwanted icons, it just turned them into question marks.
If I go into "customize toolbar" the folders aren't referenced at all:
How do I get rid of these folders and question marks?
