Its a Logitech 104 key PS/2 keyboard, using the standard Vista drivers (brand new install of Vista) and no 3rd party apps. The only apps I have running are the TrackIR software, Saitek profiler, Fraps, and Nod32.
I've tried with Nod32 disabled and enabled and I've tried running BS as admin. Vista's UAC is disabled. I haven't made any changes to the files in ..\Config.
I'm assigning and playing in simulation mode. This is how my keys map:
"=" maps to "Prev" and then works
"[" maps to "AT" and doesn't work
"]" maps to "["
"\" maps to "]"
None of my keys will map as "\"
So I have to use "]" and "\" for the tracking gate because they map to "[" and "]", and move the radio key from "\" to RCtrl Bkspc.
I'll try clearing an Abris key later and see if I can map one of the trouble keys in its place... but I think I've done something like this already.
