Mike,

A page Fault is a memory allocation error. It means that VFP tried to read or write to a memory location that was occupied by some other apps data. It is most commonly caused by errant video or printer drivers. You can diagnose it by setting the video driver to standard VGA that ships with windows and see if the error stops, if it does then the video driver is the culprit and you need to get a newer one from the video board manuf.

If the error continues with the VGA driver, then try canging the printer driver to the generic printer and see if that solves it.
