FYI: It crashes also if one clicks onto an active floppy drive
which doesn't have a disk image inserted.  In this case TOS
returns -1 from Dfree() in D0 and DISKINFO struct contents are
zeroes (i.e. this is different from GEMDOS HD emu case), so I
guess the program doesn't check error code properly.

(With normal TOS 1.04, one needs to cancel "Drive not responding"
dialog 2 times before Dfree() returns, with EmuTOS there's no
query.)

No.

I tried latest EmuTOS 512k CVS snapshot and TOS 1.04.  Same happens
also with TOS 2.06.
