There should be a key defined to pause the device, so the normal spacebar+mouse control works then.
Just look up that key in the TrackIR software. Mine isn't standard and I have forgotten about the default one. 

TrackIR5 is excellent. Needed a to set it up a little but when done I don't expect to fly it. Works great with CPT Sim but not so good with stock FSX aircraft. It seems that when I try to sit back I end up behind the seat. Thanks once again for the info.

May I suggest the clip on for your headset. The TrackIR 5 I ordered did not come with it so I went to Natural Point and ordered it. I think after shipping it comes to around $45.00 (no need for a hat)

I had the problem you are having at first with the head movement. Before firing up FSX Open the Icon on your desk top for Track IR. You will see in the calibration screen sliders that allow you to adjust the settings. MOST IMPORT! look at the top screen and you will see 3 green dots. Once you are comfortable in your chair manipulate those 3 dots by phyically moving the IR reciever on top of your Monitor so that they are centered in the screen. Now look at the 3d head image and hit F12. It will automatically center your 3d head image in the screen. From now on this will be TrackIR's reference point for center. It does take a while to get use to it but the rewards are worth it.

I think from the sheer experience, TrackIR 4 equals the #5, so no need to upgrade. I have the "5" though.
But I can recommend the combination of EZCA and TrackIR, giving you an easy and always fitting setup for viewpoints of all kind while also enabling some nice effects to avoid the rather static impression of flight sim cockpit.

So TrackIR "pure" is fine, but with the Naturaltrack software alone it's a pain in the a.. to get around some sim limitations for example.
Also, setting up the viewpoints via EZCA is much more comfortable and better fitting than any pre-defined viewpoint which can only be accessed by pressing "A".
I'm e. g. enjoying it very much in planes like the 727 and 707, really finding my spot to operate the FE panel.

Oh there's much to adjust, but I'm working with a close to default profile here. I think that Bojote offered his as a download, maybe it helps you, Sanal.

Did anybody tweak that cap to a Captain's hat? Maybe Lou attached those TrackIR reflective things to his old one. Just assuming. 

No problem. Since I've already asked Lou about his sim flying dress and he responded that the times of the white shirt and the tie are over, I'm ok.
Guess what I'm wearing then.  

But seriously, some Captain's hat as a TrackIR device would be cool or not?

CoolP,
