Love Celestia - Neat program

Everytime I approach a planet, OSX freezes and I need to shut down and reboot. I have tried to approach Earth about 10 times and have crashed everytime when I get within a million or so km. Any fixes or ideas ? Please - not too technical I'm not a programer.

i-Book OSX 10.3.5 933MHz, 640 mb RAM, ATY,RV280M9+ VRAM (Total) = 32 MB

I'm having the same problem. Switching-off ring shadows fixes it for me.

I checked and the shadows were off. I find that it almost always craches when I use the "Z" to slow down. Everything seems to run well until I hit Z.

I crash during the demo or anything else I do

I modified the config file like the post under demo crashes explained and it works fine now

javascript:emoticon(':D') I edited the config file as you recommended and it works like a charm !! No more crashes Thanks for the advice.javascript:emoticon

I had exactly the same problem, also under 10.3.5. The fix suggested works for me, too.

On an unrelated note: when is the Celestia 1.3.2 for MacOSX coming?

Can anyone repost the the fix? I cannot find it.

thanx

The "fix" is to tell Celestia not to use the buggy "vertex program" feature of the OpenGL drivers.

To do this, edit Celestia/celestia.cfg and remove the # from the beginning of the line that says

# IgnoreGLExtensions [ "GL_ARB_vertex_program" ]

It's only my G5 that suffers from "GUI freezes" on celestia, I don't encounter any problems on both my iMac's (17" & 20").
The G5 has a radeon 9600 pro card and the iMac's have NVIDEA GeForce cards.
My G5 was tested with a NVIDEA card borrowed from another G5 and Celestia ran fine on that configuration, no fixes applied!

My G5 has shown the same "freezing" symptoms also using other (including apple-) software with the radeon card on all Panther releases!

I wouldn't be surprised if the whole problem lies in the ATI/Mac combination.
