I've seen this problem before, but I don't remember the solution.

- Launch form A
- Launch form B
- Move form B around on the screen and its ghost image appears in form A

Note that FormA.Lockscreen = .F.

Now, here's the weird part

- Launch form B
- Launch form A
- Click on form B to make it the active form
- Move form B around on the screen. I get the expected behavior. No ghost image appears.

Any ideas?
