Did you design the form with a lot of colors enabled? E.g. your display was set to true color, whereas your customers use 64k or 256? Forms will map colors - may be slow. Same for rendering; don't! (numbers

One more sign of display characteristics - design with 800 x 600, 256 colors, max.

That may be extensive triggering! Try debugging you form, see what code gets executed when navigation is performed. Watch out for W-N-I triggers!

Is 128MB enough for a mainframe? What are you running? XP - No! W2K: perhaps not, W98/Me: well..., probably, W95: certainly. DOS? "there will never be a program that requires more that 640kB of memory, so this so-called border isn't one."

Scrutinize your triggers!

Certainly!
