Hello Everyone, I'm a new member just registered. I have turned to this form cause I'm not sure what I should do to fix my problem.The Core of the problem is this in FSX. When in Virtual cockpit and using the TrackIR I can not move myself up and down in the cockpit using the keys, Shift+Enter and Shift+Backspace. If I don't use the TrackIR the default keys for moving me up and down works fine. The Obvious would be of course is that those keys are clashing with the TrackIR. I emailed TrackIRs support and there response was talk to microsoft. So I did, and Microsoft directed me to here. Of course, here I am. I have tryed re-assigning but that doesn't work. The aircraft that I'm flying in FSX is the Virtual Reality Simulations F/A-18E (An awesome.awesome piece of crafting) with the TrackIR and using Thrustmaster HOTAS Cougar. I don't think its necessary to give you all the computer jargon knowing that its now a hardware issue. Please help its an annoying situation. I Thank-you Truly Craw
