Hey there, everyone. Very odd problem. First off, I'm very capable on the Mac so this is driving me nuts. Everthing will seem fine for several hours then for no apparent reason I lose the ability to copy/paste AND the ability to drag a file or folder. Its been this way since installing 10.4. I did an archive and install. If I restart or simply log out and back in, the problem goes away for a while. I've updated my added PreferencePanes and apps that I run and I've run DiskWarrior. Does anyone have a clue as to what's going on. I'm getting to the point where I think I may have to do a fresh install. Thanks in advance!
