just turn off the printer and the app (*should*) get a port time out... (or less likely crash horribly :)
And that's pretty much what happens near everytime I turn it off with my current setup, the thing never times out and just hogs CPU resources until I manually shut it off...
Anyhow, thanks for the workaround xlsior, didn't think of .bat'ing it, got me a new permanent desktop icon now!
