I'm getting a minor graphical glitch. The backdrops for units in the unit creator, or for the sovereign, are not scaled to fill the window. Instead they're in the top left, taking up about 70% of the window, with the rest of it filled black.
Graphics Card: ATI X1950PRO, latest Legacy Drivers. Ati is no longer updating them, although the card is dx9.0c compliant as far as I know.
(Unfortunately this bug report doesn't come from my main PC, on which the backdrops are drawn correctly. For this particular machine, I won't be able to get a screenshot for a week or so)
Edit: Updated to Beta 4A, still having the problem on this machine. Will get the dxdiag when I can.
