The new keyboard was completely misbehaving... I suspect it didn't like the KVM switch too much. Left-shift movement works just fine... it's only the right shift. Which makes gaming a challenge, naturally, since while hunting for salads, I ned to be able to move and cast those *storm spells at the same time...
Guess that's what I get for buying those "free after rebate" keyboards
I may have to spend a couple of buck for another decent keyboard. We'll see....
