Remove the FMain's Arrangement from the BuildForm() sub, remove the trigger timer, and replace the BuildPlayArea() sub with this:
Public Sub BuildPlayArea()
hPlayAreaPanel = New Panel(Me)
With hPlayAreaPanel
.Arrangement = Arrange.Row
.Expand = True
.BackGround = Color.Blue
.W = Me.W - Me.Padding * 2
.H = Me.H - Me.Padding * 2
End With
Me.Arrangement = Arrange.Vertical
End
... and voila... don't ask me why
