Shoutbox

nx01rules, surely something like this pseudo will work?

IF bye message recieved THEN
       IF contact window with that particular contact open THEN
       show session closed message in conversation window
       ENDIF
ENDIF

the nested if statement means that the following IF is only run if the first one is true. obviously i dont know how exactly you're coding it, so thats just he basic structure i would use.  that way the message isnt shown after the 60second time out for DP updates and stuff. hope that helps?
