>Is there any other way to get whatsthis help with pop-up windows? or does anybody knows where to find "Windows Help Workshop"?

If you look in the last couple months of FoxTalk, there was a series of articles about adding pop-up windows to your application.

Otherwise, try looking on the VFP3 and 5 CDs for the Windows Help Workshop. Or the link here:
