The test case results in a form with no active control.

The problem is MDI-related, because MDI children will not receive a
Form.WmActivate message. (The test app will work ok if you comment MdiParent =
AppDesktop.MainForm;).

According to the ChangeLog, on 2007-01-10 a call to SelectActiveControl was
removed from Form.OnCreateControl because it was unnecessary. This call might
be necessary for MDI children. Something like:

if (this.MdiParent != null && this.ActiveControl == null)
        SelectActiveControl();

will fix the problem. Or perhaps this call should be made somewhere else, just
not Form.WmActivate.
