I recently received NeoDesk 3.01 for my STE and have noticed an
odd behaviour, I don't know if this is planned, I can't find
any explanations in the docs....any help appreciated:
 
NeoDesk in A: and some other disk in B:, if I play around with something
in B:, then quit to the desktop, and close all the windows for B: then
eject the disk and put in another one, then double click on B:, it seems
to read from the disk (light goes on) but displays the OLD B:'s directory,
or sometimes it just shows up a bunch of files with garbage characters
for filenames.
 
Anyone have any idea why this happens?  I can correct it by typing
escape once I have the B: root window open, then it behaves as normal...
 
Running on a 4meg 520ste, if that matters.
