I think that one of the changes made with system 4.1(?) was to fix CopyBits so it wouldn't assume the stack was infinite, and now it takes appropriate steps to copy without writing into the heap. So you likely don't need to worry about it. --Tom Lippincott ..ucbvax!bosco!lippin This posting is being sent to thousands of machines, throughout the civilized world!
