Hi

yes, the current behaviour is to load the whole disk image (~720-880 KB) 
and keep it in ram. And when disk is ejected, possible changes are 
flushed to the disk image.

So, using a concurrent program at the same time will certainly not do 
what you expected.

Maybe it could be flushed after every write, or after 1 second of non 
disk activity, to get sthg closer to a real floppy (ie changes are 
visible just after being written)
