Ok, I've had my TIR3Pro with vector for a couple of weeks now, and was always having trouble keeping the view from snapping around uncontrollably. Finally someone suggested I use the old 3.1.1 software instead of the 4.22 beta I'd been using since I'd installed TIR. The 3.11 not only wouldn't work, but even the TIR itself wouldn't turn on! Something about not being able to find the drivers. Finally after much thought and many reboots I reinstalled the original software that came with the TIR and since then it's been doing fine! What I should have done in the first place is tried out the product they sent me without dinking around with beta's. I would have noticed that it was running fine and NOT tried to fix it!!! I don't need no help, just thought I'd mention this to all new folk so maybe they'll save themselves some frustration. Cya'll in 'da skies.
