Every time I exit out of the user preference menu it exits out of Blender completely. I changed it so I can view it in the main window. However in one of my files, the window is stuck there and it appears black and eventually crashes Blender. When I exit out of it, it exits out of Blender too. Anything I can do to get rid of it?
NOTE: It was also doing this in 2.74 as well.
