i have a very similar problem to someone else on this board. i am unable to drag objects, whether it be on my desktop, in a folder, or even in adobe illustrator. this problem began right after a friend of mine tried installing an icon program called candybar on my computer. he quickly erased it when we saw the problems it was causing, so it was never even installed; it just sat on the desktop for 10 minutes.
however, the dragging problem is not all the time. it happens when i insert a cd or dvd. whenever i do that, any programs that i happen to have open shut down, the finder relaunches itself, and suddenly i am unable to drag. also, the appropriate programs (itunes or the dvd movie) do not automatically open. but when i manually open them, the cd or dvd reads just fine, but the lack of dragging persists.
i have not yet backed up my files (and there are a lot of them, as i'm a graphic designer), so any suggestions that will not endanger my files would be greatly appreciated. if there is a chance that my files could be lost, please alert me so that i don't try a suggestion and end up an unhappy girl.
thank you so much
and that disk permission thing didn't work

any other ideas?
