You must, of course set form.keypreview to .T.. keep in mind also, that this method does not detect mouse movements. You could put some code in the form.mousemove event, but this would be too much overhead for my liking.

Basically, it's about what means 'inactive' form from application standpoint. Remember, that user can switch to another Win app, leaving VFP app on background.
