Ellen,

What is your operating system. If you're running 95/98, 64 Mb of memory should be sufficient, but w/ NT 4.0 it's barely adequate. You say there's no code in the InteractiveChange. Is this true up the Lineage-line? Is there any difference between a TextBox based on VFPs class and one 3-4 levels of inheritance deep?

I've noticed problems w/ MMX chips regarding display. Is there any difference between your 166 and 200 in any regard besides speed rating? ie: one is a knockoff...

It sounds like an "Interesting Phenomenon". That means it's happening on your machine. If it was happening on _my_ machine it would be a "Big Damn Problem"!

>On my app(that I converted from VFP5) on a P166, w/64M RAM, just tabbing thru the controls is slow (even tho it's not hitting any code). It is also sluggish when I enter data in a text box. In fact, I can get 3 or 4 letters ahead of seeing them appear on the screen(no code in the interactiveChange)! Neither of these things happen on my P200.
