Are you using a background image of some sort? Like adding an Image to _screen or setting _screen.Picture. If so just do a ?? "" after you set the image.

>I have a development system at home PII400 128Mb with Windows NT sp4 installed on it and VFP6.0.
>When I drag my form in the normal Fox environment, command window, form designer or property sheet they seem not to follow right away and then they bump along following the dragged mouse pointer.
>I already tried to reduce the refresh speed of my video kaart and monitor still no luck.
>I remember reading somewhere that screens became slower as of VFP6.
>But I'm wondering as well that it is not just a simple windows setting that I can change (something like the double click interval for the mouse or drag full window). I just don't know where to look exactly.
