>I didn't use a builder (it a class-based form), but even it it was set at design-time, it's unset at run-time, so why would the design-time setting matter? Is there some kind of VFP glitch that overrides the run-time setting of LockScreen or something?

Jeff,

I've had exactly this problem. It generally happened on interfaces with pageframes, and a grid in the second page, but the transparent rectangle was completely random. We found that if the interface was moved off the screen so that just the header bar was showing then moved back on the form was repainted and complete. Thinking along the same lines as yourself, we tried issuing a paint call without any success. Finally, just by luck, we discovered that if in the activate of the form the following code was executed the problem went away. I know it doesn' make sense, but it worked..

THISFORM.Lockscreen = .T.
THISFORM.Lockscreen = .F.
