OSX chokes after disconnect from another computer

[Paul Korntheuer]

Is this a known bug in OSX? If I connect to another computer (via SMB) 
running XP or Win2kPro and one of those computer(s) that's on my 
desktop shuts down without notice, if I click on its icon after its 
shut down, OSX chokes with the pizza wheel of death and then goes blank 
with a grey screen (am I allowed run-on sentences?). Not a graceful way 
for OSX to state - hey, I thought that computer was still active!

Does OS 10.3 fix this problem?
