This is a strange thing that is happening. We are currently testing the upgrade to GP2010 on our development environment where GP app and Citrix reside on the same system. The GP app on Citrix does not work when trying it from a user’s system and crashes when trying to load the GP home page. Now, if we use another system and RDP to the same users system and then login and try the GP app it will load up just fine and not crash. Both ways we were using the same user credentials to log into Citrix. Has anyone run across this issue or similar with a different app?
