Hi Rassilon!
I downloaded you addon and the "qt" file, but in my PC at home I only see a window (non centered in the screen) with a picture on it, the hourglass and nothing else...
My PC has Windows XP Professional (Athlon 2.7+, 1GB RAM) and my graphic card is a Sapphire ATI 9600 with 256 MB

RAM onboard: Celestia works wery well with no problems, so I wander what is happening
FYI The window I obtain can only be killed by means of Ctrl-Alt-Del Task Manager that informs that the task is not responding.
BTW The "exe" file has the "small window" icon , the icon DOS programs use... It's strange. It seems that the file is corrupted
Now I'll try to reload the add on and then I'll tell you
Good bye
Pierluigi
