3D plots won't display

[GrahamParkhouse]

The application I'm using on Mathcad15, well used by others with none of the problems I'm about to describe, won't display any of its 3D scatter plots on my PC. The plot area basically shows white. But if I drag the cursor around the plot area or use the scroll wheel, occasionally an image flashes up momentarily, and disappears too quickly even for recognition. But I suspect I see bits of the expected image.

Has anybody encountered this problem? Has anybody got any ideas how to fix it?

My PC is a Dell XPS M1330 laptop running under Windows 7. The graphics adapter is a Mobile Intel(R) 965 Express Chipset Family. But my problems seem to be confined to Mathcad.

Thanking you in anticipation.

Right click on the plot and uncheck "Border".

Unchecking 'Border' has done the trick! But why?

Thank you so much for the answer!

But why?

You are not the first to report this problem, and turning off the border seems to fix it. I don't know why. I assume it fixes some conflict between the OpenGL graphics library used for the 3D plots and some video cards.
