I received TrackIR 5 with TrackClip Pro last week and it's been great...until I decided to try the non-beta v4 software.
If I use the TrackClip Pro with it I also get the lockups/no tracking to the left and up problems I see mentioned by others here in the forum.
I do have the TrackClip Pro selected in all the profiles and I've also tried the standard recommendations given to others but the problem persists.
One question that I do have is if you have already installed the v5 beta software and then install the v4 (latest build) should you install the usb drivers when you install the v4 software? I did and maybe that's where the conflict is...or do the 2 software packages use the same drivers?
Any help would be much appreciated.
BTW, I look a little goofy wearing a hat to use TrackIR... I never wear a hat in real life.
