I am also having another issue if you wouldn't mind helping out. I am playing on a 5 star, 102 planet map. I have a maxed fleet. When I travel to another star system, it will let me zoom in enough to see the pathway between planets, but I cannot actually zoom to each planet to see what is there. It doesn't crash, it just stops zooming at that point. I can then zoom back out just fine but cannot zoom in any further than being able to view all of the planets.
I am running:
6 gigs of tripple channel memory
Nvidia GTX 280
WD 74 raptor hdd
