The MS hotfixes and registry setting were applied. The Citrix hotfix was not applied because I have the behavior even though that feature is turned off. -----Original Message----- From: Erik Gerard [mailto:GERARDE@xxxxxxx] Sent: Thursday, October 03, 2002 4:15 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: latency Did you try the two MS hotfixes and the necessary Reg edit?

I have done some searching on thethin archives, and found reference to "a small program that measures latency" but I was unable to find this tool in the downloads.
