Does nobody ever read the thread at the top marked "
Read This Before Reporting a Bug"?
It's not good enough to just say "it crashes". We need to know what OS you're using, what version of Celestia you have, what hardware you're running it on, what video drivers you have installed, and exactly what you do that seems to be causing the crash.
Come on people, please think before posting these things. We shouldn't have to play twenty questions asking about your computer setup before we get to the point where we can start to figure out what's going on.
