Every once in a while on Powerbook 165 running 7.1 I get a prompt to insert a floppy that I have don't have. Any key press combo to clear the prompt? Example: I put a floppy name MISC in the drive , copy some files , then format and eject the disk. It leaves a greyed out icon of the old disc on the desktop. If I click that icon it prompts to insert the disk. Other than inserting the disc, can that prompt be cleared with some key presses , as it seems to lock up the machine?
