Draftsight 'vanishes' on opensuse 12.1 x64

Hello,

I'm pretty much keen to switch from my traditonal cad software to draftsight but I haven't been able to "see" it's main screen for more than a second yet. I downloaded and installed the rpm package. The installation and activation were both successful. However when I try to run the program it appears to work for like a second then simply vanishes. Has anyone got an idea how to solve the problem?
