I have an AMD Athalon XP 2800+, an Nvidia GeForce FX 5500 AGP, Windows ME, the latest drivers, and version 1.10X.
Roughly 50% of the time, after I close the game I get this error:
Ddhelp has caused an error in NVDD32.DLL
It seems to be completely random, and not based on any in-game actions, but the last portion of debug.err has a few possible clues. I have copied the closing portion of the file, starting once the quit messages are posted:
Debug Message: OptionsWnd: Quit Btn
Debug Message: Posting WM_CLOSE message.

Debug Message: GameUninitialize end
Debug Message: Device not cleared. 32 counts left.
Debug Message: D3D not cleared. 1 counts left.

The third and fourth to last lines stand out to me as possible clues.
The second problem I have is with the in-game movies. The intro is fine, but the in game movies (first anomaly, civilization dead, etc.) have major framerate problems. The sound plays normally, but the movie will freeze on a single frame for an extended period of time, often over ten seconds (but sometimes as small as half a second), before it moves on to the frame it should be playing. The frames that do get shown are synchronized with the sound, and the movies seem to have no other issues except for the slide show effect.
The final bug that I have found involves number temporarily jumping to insane values, but going back to a reasonable range after a few turns. This seems to be related to an event occuring, such as the time I invaded a planet and had its population jump to either four trillion or four quadrillion, depending on whether the main screen or the planetary report was more accurate, but then it dropped down to a more resonable .5 billion after a few turns. Another case of this bug occured when I made peace with my long-time enemy, the Arceans, and then had their influence mysteriously jump up and fill the entire galaxy for the next 3-4 turns, forcing me to lower taxes to keep my planets loyal until the Arcean's influence returned to normal values. There may have been other cases of this, but these two incidents were very obvious. I will take a guess that this bug will be difficult to track, since unless influence and population are not recalculated on every turn (or there is a lot more going on than meets the eye when they are calculated), there isn't any obvious reason for the numbers to go so high and still be able return to reasonable values later on.
