Everytime I try to empty my trash, my mac mini just kinda sits there and locks up for a few seconds, and then says "Finder could not complete this operation because some data in 'gfx' could not be read or written (Error code: -36)" and gives me the option to continue or stop. If I continue, everything BUT one file gets removed from my trash. The file in question is a copy of iTunes that managed to get corrupted when I did a system update. I have iTunes functional again, but this old corrupt version seems to not want to die! Help.
