I finally maked a better version of my last image with a particular shape and tried it on Windows XP SP2 and then Celestia crashed. I enlarged my image with a transparent edge so that width is bigger than height and it ran !

This time, I uploaded a png file with my desktop screenshot.
Is a way to move Version and Loading lines ?

We could continue to improve it with little round corners...
