Maybe it's a bug, or maybe just my system, but when i try to move shortcuts within CS menu into folders, to organize it a bit, it freezes and i have to kill CS in task manager, which still doesn't make opened CS with menu structure to go away, but when i start continually clicking allows force close and shell restart.
I'm using Windows 8 x64.
Which version of Classic Shell are you using?
I think I noticed a similar problem. Right clicking on some of the shortcuts in the menus may hang CS sometimes. I know, it's very vague, but what can you do?
I use version 3.6.4 now. I didn't notice this problem in 3.6.2. But I cannot be sure it wasn't there.
