Meh. Blender is buggy as hell. You just get lucky. My blender won't recognize that my drivers are updated so I have to guess when i'm box selecting and i can't see the connecting lines in nodes editor and such. I'm going to go google my ass off in hopes of finding a solution.
I haven't yet had any problems with my blender, so I respectfully disagree that Blender is "buggy as hell", I haven't experience any bugs myself, so it can't be buggy with no bugs right?
PS: Judging by the fact that your signature says "graphic coming soon", I'd say you want an image there, well don't get your hopes up or work too hard, you can't have siggy graphics on this forum.
