I have installed the version 1.5.0 and all the planets and the moons appears as big red circle, without any details. The previuos version (1.4.1) worked perfectly. My system is a Windows XP version.
Can someone help me?
Thanks
Marco
Unfortunately, that is a symptom of having obsolete graphics drivers. You need to download and install the current version, which should be available for free from the vendor of your graphics hardware.
Thank you very much of your hint. I have updated the driver of my graphic card updating also the OpenGL library and now Celestia 1.5.0 works perfectly
Bye
