Excellent game, by the way!! Here are some bugs that I've noticed while playing

1-Population growth does not double when Approval/Morale is at 100% (pop. seems to grow/shrink correctly at other approval levels)

2-Mouse disappears on occaison when alt-tabbing as well as during screen transitions (i.e. after a technology is finished researching) and double clicking planetary improvements. In an 8 hour gaming session this bug occurred 4 times. Sorry I don't have a step by step to reproduce it.

3-The random event timer seems to be off. During my first 7 hours of play I received two good/evil events from colonizing and one good/evil random event. Then in the eighth hour I received 7 Lucky Ranger ships in a 10 turn period of time. My race had the lucky bonus as well as Universalist. I also had creative and received no apparent benefit from this.

My system specs are:
Athlon 3200+
2.5 gig RAM
320 gig hard drive
Geforce 7800 GT
Logitech iFeel Mouse

Hope this helps in your debugging efforts!
