This is a serious reply <*bg*>
For Win9X/ME you can trap it by enabling screen savers ( SystemParametersInfo API )
For NT4/2K/XP, there are several ways but none of the solution can be done from VFP not even from VB. The only solution is replacing GINA.DLL. If you want to experiment with this, setup one test (unused) machine because playing with GINA can make your computer unusable (very RISKY!!).
Platform SDK: Authentication (GINA)
