swabby, I'm running win 2k and it seems to crash randomly on me as well... albeit a little less frequently when I am using "random ports" option (I did a little messing with every option to figure out what may be the cause - this slowed the crashes)... I have a couple of the Dr. Watson generated error logs if they would help at all for debugging... I will admit all of my crashs have occured while the program is minimize to the sys tray...

As for background apps... ussually running
