Discovered DraftSight and installed and activated it in windows and Fedora 14- 32 bit without problems. But in Fedora 14-64 bits after installation view area is not visible neiter accesible with the mouse. From the command line I get:

\\\$ ./DraftSight

My graphic card is a nVidia GeForce 210. I tried both in Gnome and KDE with same result.

Many thanks.
