There isnt any code in the evnets or methods of the active x... I think it might be related to how fox updates the pixels on the screen... Someone once posted how fox does that... blt by blt or something like that... I remmeber that someone was talking about citrix and how you need to set bitmap off in the config.fxp to stop unecessary entire screen refreshes ??? Maybe its refreshing the entire control when its unneeded
???
