Hi Peter, are these files by any chance on a network drive? If so, that's standard procedure. If it's just from your internal drive and your user account, this link may be helpful: Resoving Trash Problems
I once helped a friend make an INIT (remember those) for MacOS 7, and it turned the lower right of the screen into a sensitive area, so when you dragged a file close to the trash, but not into it, it would move a pixel closer every day until it "fell" in. thus automatically cleaning up a corner of a cluttered desktop (Euan please note...!!) never really caught on though.... but a great idea no?
Clutter, Gordon? I don’t do clutter (ahem). When I was very young I had a ‘bottom drawer’, it grew into my house and has finally reached my desktop -- which is actually quite well organised (he bleats) and works on strict and known principles.
You should re-write your init for Mark who is the greatest known specialist for weird happenstances if the mouse strays into screen corners and other booby traps. Never offer to show anyone anything on his screen -- as Apple would say: ‘results may be uncertain’.
But, having put up this spirited defence of my bad habits, yes, you should re-write it for OSX. I predict viral delight -- worldwide!
