Mr. Kevin Glover,
There were a few issues:
1. was a problem with the TrackIR locking the mouse in game (Windowed-mode) so that it would prevent the scrolling of the text dialogue boxes on the IE browser. So, when you would type a message it would automatically scroll the window to the top of the dialogue, per each character you type. I also use an in-game utility called InCabin browser which allows for opening of approach plates (.pdf docs) and other files (.jpg's, etc.) and it uses a Browser interface. I noticed that this problem affected it as well. It did NOT occur with earlier versions of TrackIR, so, all I can do is assume that the v4.1.037 has issues.
And, TrackIR v5.0 is worse; it ceases functioning for time to time in the game causing rapid head movements that are NOT initiated by the users (in a pitch-black/dark room). Then, if you try to close it down (while still in the game), the app shows a dialogue box indicating that its closing but it locks up there. I have to use Task Manager to force a shutdown; so I gave up on it entirely and have stayed with v4.1.037, which too has issues mentioned above.
2. Also, this would result in FSX crashing (CTD) in ver. 4.1.037 when things got overloaded. I would have to shutdown TrackIR and restart it as it would not re-initiate after I reloaded FSX after a crash.
3. There were other issues with FSX's Force Feedback kicking in and shifting the stick rapidly to a bank; something that didn't actually bank the aircraft in FS. I resolved this by using FS Force v2.11 instead of FSX's force feedback.
This is all I know to tell you about it; still think its funny?
