Rare game crashes may be experienced when a player engages into planetary battle mode. They are observed in native windows systems too and are not due to wine bug or any issue of this sort.

Planetary battles and windowed mode

Planetary battles works in wine 1.3.4. To run the game in windowed mode you may want to enable virtual desktop emulation in winecfg and start the game in fullscreen. Very useful for games that doesn't support windowed mode
