Thank you for your response.
Concerning the drivers for the TrackIR and the Realtek NDIS Protocol Networking, I can honestly say I was genuinely under the impression I had found and installed the newest drivers available.
Beyond a shadow of a doubt I can confirm this for the TrackIR as I have been at their site and have tried the latest drivers for both the TrackIR 4 (which is the unit I have) and the TrackIR 5 ..... I have even spoken with one of their technicians who told me both were compatible with Windows 7 yet here we are with these results.
As for the Realtek NDIS Protocol Networking Driver, I thought I had found the right file / files but this leaves me more confused than ever and I am unsure what to search for.
For my anti-virus, I use Avast which I update and run full checks weekly: avast! - Download Free Antivirus Software or Internet Security
For my firewall, I use Vista Firewall Control made by Sphinx Software: Windows 7 Firewall Control : Sphinx Software
I can change this to their Windows 7 version but liked the interface for Vista better so I kept it ... I was originally on Vista and then upgraded to 7.
I'll await further responses / recommendations.
Should I simply wipe my C Drive, buy a full copy of Windows 7 (not the upgrade from Vista) and simply start a fresh or will I simply have these issues again?
I have not heard other TrackIR Users complain about crashes with Windows 7 so could it be something that doesn't bode well with the Vista-to-7 transition but might not happen in a Windows 7 fresh install?
Thank you for your time.
