First off fyi, I've switched to Nautilus for my window manager. When I go into the individual app properties (to customize the icon), it brings up the window manager (to find the icon I want to replace the default icon)... but it locks up (won't let me select anything in that window). Am I doing something wrong? I've duplicated this on two different computers, so I know it's not anything with my computer. Thank you in advance for your assistance with this issue.
