>I upgraded to Windows XP recently and installed a fresh copy of VFP. The problem is that the online help Menu is greyed out and is not available. I installed MSDN Library full.

The last version of the MSDN Library that worked with VFP (or Visual Studio 6) was the October, 2000 version. Go to Tools | Options | File Locations and make sure your Help is set to the VFP Help as was mentioned elsewhere in this thread.
