Regarding that scroll bar thing, make sure your video drivers are up-to-date or change to something else, if you have options. I don't think I've seen that, but have seen other refresh issues. As for scrolling in code windows in VFP, I've noticed that if you're in the middle of a fairly long code method, say 3 or 4 pages, and you just click the elevator button (Mac terminology!), the code will "jump" a little. It will move up or down as soon as you click (holding the button down, but holding the cursor position steady). MS Word and other apps do not exhibit this behavior. Then yesterday I had a form open and opened the data environment. I changed the BufferMode property for a table and the form (still visible behind the data environment window) exhibitied some strange behavior: some of the controls disappeared. It was kind of like I'd taken an eraser to the form. A minimize and maximize made everything visible again. I did this a few times and it kept doing it. This was VFP 8 SP 1.

Your English is great. Where did you learn it?

>I am pretty sure this happens only in VFP. I've also encountered another situation: I have a form open in Form Designer, doubleclick something to open the method code window, and, if the window has a vertical scrollbar, grab the scrollbar, scroll down it a little, stop the mouse but keep the mouse button pressed. That's it, the key point is to not release the mouse button. After few seconds (I don't know, maybe 3, maybe 5, something like that), the visible windows become white, no content is shown, and periodically some sort of _screen.refresh occurs. It looks like a timer code to me.
