Alpha Transparency in the Development Releases

[marty4286]

Last month, a windows update (the only culprit that made sense) caused 1.5.4 to be unbearable to use by screwing up antialiasing -- it began applying it to the menu text (making it extremely blurred) and stopped applying it to the 3D geometry. The only thing that fixed this issue was uninstalling 1.5.4 and installing 2.05. Perfect! The new UI looked gorgeous and it even ran faster for me.

The only downside is that alpha transparency in textures is now rendered as solid black by the geometry and show image windows. Is there anything I can do to restore transparency? I reinstalled 1.5.4 briefly and it still shows up transparent there (the antialiasing problem is still present as well, so reverting is a no-go)
