Here's is a cool bug in explorer. Notice no name column, and no way to "remove" it and then put it back. COOL! Too bad I don't know the steps to repeat the bug. =(
What I think happned was that the name colum was resized to zero width. If this happned to the size column, you could just remove it, then put it back to fix it. But since name is dissabled, you can't fix it that way. OOPS!
