Loriath,
I apologize if you spent any time on this I'm a bit embarrassed to say I have found the issue. Voice Attack needs the NumLock key off, especially if you have TrackIR running as it gets a bit jumbled. Turning it off has now meant I have a fully functioning system.
I am also now running the beta version of Voice Attack, I suppose it could be that that solved it, or that may be my cop out for not spotting it earlier!
Sorry to have troubled you.
No Worries. Glad you got it sorted. Guess its more an issue with the TrackIR as my Numlock is always on. I am running the Beta as well as I built a simple Voice Dictation for Comms in Game.
I'll be glad when Arflint gets back and reopens the Website. I may have to send him a bill for Tech Support
