I guess it's the usual 'opengl' problem but I can't find a work around. The error message returned is: 'Celestia has caused an error in TRIDICDP.DLL'
Have looked in 'glsetup' but unfortunately there's no match for my graphics card there. I'm not even sure how to find out what graphics card is installed in my machine

Interestingly, OpenUniverse works fine
