If I press my two shifts and the w key, it works. If I press my two shifts and the q key, it does NOT work. It happens with few random keys. I sniffed with wireshark to figure out I still receive a ErrorRollOver.
Okay, my board isn't NKRO, it's a unicomp spacesaver. But I should be able to do it too, no*? It's two modifiers and only one normal key. I don't get it. It's the same with other keyboards too, though not with the same keys. Depends of the matrix I'd say.
