BUG:Problem with Combat Summary popup

[mikemike]

I played Coral Sea as Japan against Allied AI. Start parameters are -deepcolor -altFont fullscreen. When the Combat Summary popup has a scrollbar, if you put the mouse pointer on the scroll bar, hold down the left mouse button and move the mouse pointer sideways, the text will scroll horizontally. You usually end up with a varying vertical slice of the text permanently vanished out the left edge of the window. This is repeatable.
