I haven't seen this described anywhere, which may say more about my searching skills than anything else.
When I fired up VFP9 in Win7 (64, although that doesn't seem to matter), I was irritated by the annoying screen flicker as I moved IDE windows around. But I was always too busy to get to the bottom of it, and it was only irritating rather than actually standing in my way.
Today I had a few spare milliseconds.
If you right click the IDE executable itself, select properties, select compatability and, under Settings, Disable desktop composition (whatever that means), this annoying flickering goes away.
You get a funny message from Win7 itself saying, essentially, it's turned off AERO for the nonce. It turns it back on when you exit VFP.
Maybe everyone else knew this already, but it was news to me.
