This causes Citrix to resend the entire screen everytime a textbox changes its value. With the deve tools that use windows objects Citrix only sends the changed control for display.

FWIW... I have between 10 and 20 users running a pure VFP app over Citrix every day. We actually realized a tremendous speed increase (probably because the Citrix serve is a dual 300 mhz box :))

There is only one instance where VFP seems to bog things down and that is when it's executing a SQL statement... apparently, VFP grabs all available memory to do this and Citrix allows it to. This, of course depletes the available memory pool for other session to use. Fortunately, the app in question does not execute any SQL statements during a typical day.

The app is a survey system with 10 to 20 phoners. The only time SQL is used it to build the survey. After that, it's simple IO as usual...
