>Quite possibly way off the mark but I have been using Citrix's gotomypc on a large scale for a long time - only recently it has started to display the annoying habit of changing the default printer when connected - it doesn't do it all the time - could there be any connection between this problem and yours

I made sure that the correct printer was set as the default, and it still didn't work. I sent the client version 8.0 of the Citrix client, which should solve the problem, but I hope it doesn't disable any newer functionality they use.
