Can't jump when running

[Urkle]

we access the keyboard more as a set of "keys" than combinations.. so that difficulty doesn't apply. we are simply looking at every keypress and keyrelease event. So, if no program is in the way (which many others are using unbuntu 10.04 and gnome w/o reporting this issue), then my guess would be the keyboard is faulty and not correctly reporting multiple keypresses on that half of the keyboard.

Have you tried using the right shift instead to run? I have an old Omnikey ultra (1990 keyboard, love the keyboard). that only tracks like 4 keys per half of the keyboard.. So if I press more than 4 at a time it doesn't recognize them.
