If you can't, please ensure you don't have Emulate3Buttons enabled on your X server. This translates simultaneous left- and right-clicks into a middle-click, and prevents you from firing left and right weapons on your Vulture at the same time.

(This is in response to a bug report, but I'd like to make an announcement I guess)

How did that get set? I _never_ have that set!

/me is publicly humiliated.

Aw, don't be embarassed. I had that set for a loooong time before I realized it, and even longer before I decided to do something about it. I got pretty good at timing my left & right clicks.. :P
