In most cases the game runs fine until around turn 50. Once this happens, the game becomes sluggish until it is near unresponsive. Most of the time, this does not affect the music as it will still play without bogging down. I can then close Elemental, run the game again, and play for about 50 turns before the problem reoccurs. This happens in ALL games that I start new or load from a saved file. I have checked my disk usage and know that whatever causes this error leads to a memory leak.

Also, about 50% of the time when I enter a tactical battle, the map is white with about a sixth of the left side of the screen tinted yellow. The tactical battle HUD that appears at the left, bottom, and right of the screen is displayed correctly and fully functional.  Luckily I've been able to click auto-resolve from there and get back to the strategic map. But, once the strategic map is displayed and I zoom out to the cloth map, I get this: 

The cloth map isn't presented correctly and none of the cities have their names displayed.  The units still appear as figurines though.
