Terry,

Mark already helped with Autoyield, so...

My practical understanding of Lockscreen is that it simply stops or allows the painting of the form and it's contents. For example, I will sometimes put this in the Refresh of a form:

Lockscreen = .T.
   ThisForm.MyObject1.Refresh
   ThisForm.MyObject2.Refresh
   ThisForm.MyObject3.Refresh
   ThisForm.MyObjectN.Refresh
Lockscreen = .F.

This will "pause" the redisplay of the form while specific objects are refreshed to help eliminate flicker.
