I have the same problem down here and have to open Task Manager to forcefully end Orbitron. I would like to hear if there is a better solution.

Hello Thu (and all others on the list)
Now things are working here. I post some of the advice i got off list that helped me get it running. (maybe help someone else)
*Don't install Orbitron to the default location. Save it somewhere like C:\Orbitron so that it can write changes and you can edit the files.
Also set it to run as Administrator and if you are still having problems set it to run in compatibility mode for windows XP
I'm running windows 7 and running it as Admin fixed the problem.
*I think you have to install it by right clicking on the installation file and select run as administrator, and you might have to do the same to run the program under win 7. I use a shortcut on my PC that I set to run as administrator in the shortcuts properties
*I have fixed a similar problem by running it in XP Compatibility mode. Look under the Properties for the icon.
This helped me to get at really nice program running also on my new computer.
