When i'm zooming in or out from the sun (i haven't tried it with any other stars) at about 73AU (neptunes orbit just visible) celestia locks up & sometimes I get an illegal operation message.
This is the message I got when it happened a while ago:
CELESTIA caused an invalid page fault in

All labels except asteroids & galaxies were turned on at the time, stars were set as points, but the mag was set to 0.8. (Just in case it matters!)
