lines through my icons


Every once in a while I get 4 horizontal black lines going through some of my icons. I've seen this happen with BBEdit files and with hard drive icons. With the BBEdit files, if I select them and go to the Info window and rechoose BBEdit as the application (it is already chosen, so this doesn't change anything), the icon will go back to normal. I've had a harder time with hard drive icons. I've tried cutting and pasting from unaffected icons, and eventually I can get the icons back to normal again.

Has anybody seen this? It's a minor issue, but it's kind of annoying.
Restart!? I hate that! My lovely stable OS has to be restarted just to sort out a niggling icon problem... I'll stick with the black lines!
