Are they wireless keyboards? I've seen problems when either the battery(ies) in the keyboard run out, or there is interference or a poor wireless connection between the wireless keyboard and the computer.

Is there a timer running, or an ActiveX control on any page of the pageframe or underlying form?

Any tricky code in the .InteractiveChange or .ProgrammaticChange methods of the problem fields? Any tricky code in the methods that fire when navigating from one page to another? Any automatic saving of field contents to VFP tables or some other backend? Are the fields data-bound, and if so, what is the buffering level?

Any unusual keyboards with their own drivers? If so, have the drivers been updated, and are they correct i.e. don't use a Logitech keyboard with MS drivers?

Finally, delays caused by key logging software ( http://en.wikipedia.org/wiki/Keystroke_logging ) could conceivably cause problems like this. Keyloggers could be installed surreptitiously by malware, or on purpose by employee-monitoring software such as Spector CNE: http://www.spectorcne.com/
