Visual FoxPro does not perform like a true Windows application because it does not utilize basic Windows primitives to create its screen display. When FoxPro places a box onto the screen, it actually draws the box.

WinFrame has a limited ability to detect certain ill-behaved screen painting issues like Foxpro if the
following screen design guidelines are followed:

• Keep screens as simple as possible; limit colors and color changes.

• Limit actions to 25% of the active screen area; that is, if an action changes something on the screen,
whether it is a field or a background, verify that it is all within the same 25% of the screen area.

• Do not overrun the area you are working in. If you are working with a 640x480 screen, do not let
any of your screen displays go outside of this area.

DISCLAIMER:

None of this has anything to do with us, someone else is responsible for the entire thing, and we have no idea who or why. We do not know anything about it. It may be alien life forms for all we know: we haven't a clue. You cannot blame us for anything that may result from your visit. That was entirely your own personal choice, made by you of your own volition, and without our knowledge. We do not, after all, have any control over you and cannot by any stretch of the imagination be expected to accept or acknowledge, be it legally or morally, any accountability for decisions made by you on an independent basis, utilizing your own free will, and without our intervention. We are therefore in no way, shape, or form answerable to anyone for any consequences arising from the aforementioned or indeed any other actions, similar or otherwise, because it was not us that did, or did not do anything. It is not even remotely our fault, and we are in no way prepared or willing to accept any liability, not even slightly, ever. We are, in fact completely and utterly blameless, in that it is definitely not our concern, and no blame can possibly be laid at our doorstep, even if we had one, the possession of which we hereby reserve as being entirely our own free choice. The onus is not on us at all, and furthermore, never has been. The entire matter is wholly beyond our control, and completely out of our hands, each of which are washed scrupulously clean of the whole business. We are not accountable for anything at all, and we hereby categorically deny all responsibility for all that has ever, or will ever happen. Our innocence is therefore wholly beyond doubt and absolutely unimpeachable, and so cannot, under even the remotest or unlikeliest circumstances, be brought into question. By clicking either on a link on this site, clicking on a link that leads to this site, or by arriving at this site by natural or supernatural means, you are in effect accepting responsibility for the fact that it is all entirely your own fault, down to the most miniscule detail, and that you are wholly accountable for whatever outcome may arise as a consequence of the aforementioned action or actions insofar as they were undertaken personally by you on an entirely voluntary basis and without any persuasion, coercion or influence from any party or parties other than yourself. Don't come sniveling to us, we are only figments of your imagination. I also agree that if I am ever with a contributor to this website during mealtimes I agree to pay for any super-sizing of their meal, or at least a nice dessert or one of those foo-foo drinks with an umbrella or a monkey. By admitting to have seen the worthless spineless drivel on this website (also known as content)

I Agree Wholeheartedly and Without Reservation to the above. (Except maybe for that part about the monkey.)

All Your Base Are Belong To Us.

Never make a bet with a Sicilian when Death is on the Line!

No. Really, I do agree.
