--- Comment #2 from Lauri Niskanen ape@ape3000.com 2010-05-07 10:11:52 --- I use proprietary nvidia drivers. The version is 195.36.15. I can play many 3d-games in window. For example SC2 works fine in windowed mode.
If I start the terrain view directly when I start the editor, I see my wallpaper through it or sometimes some textures from the game. If I start the terrain editor from other editor windows I just keep seeing the window as it was just before I changed the view mode. In any case the editor completely freezes.
