VFP9 Refresh problem

I’ve been having a few page refresh problems with VFP9.

I’m updating one of my programs to run in VFP9. In VFP8 page displays have been fine, but under 9 they don’t always refresh. If I manually add a .Refresh() to objects after doing something (eg adding records to a grid) it is fine, but this is something I never had to do in 8.

A bit strange. At first I was looking for a dodgy .LockScreen = .T. but it is not that. Debugging ofcourse won’t help because swapping back to the screen does an implicit refresh anyway. I’ll keep investigating. Other apps that I am running under 9 are working fine, so it must be someting in my base class code. And I’ll bet it is going to really obvious when I find it.
