I have recently discovered a problem with the file selector routines in
Allegro, which is caused by selecting disk B: on a machine with only one
floppy drive. DOS displays the "please insert disk B into drive A"
message, which results in a lockup because the Allegro keyboard handler
prevents the continue keypress getting through to DOS.

I've racked my brains but can't think of any way round this - please
someone tell me there is an easy solution :-) I need to either disable
the message, or detect whether disk B really exists, but I have no idea
how to do either. Any ideas?
