Thanks for the quick response. I have now tested for this behaviour on my laptop, and I cannot reproduce it. I tried the laptop with my wireless headset, and works flawlessly (at least for the duration of testing), I also tried it on my gaming machine with a fixed USB keyboard, but same effect.
So in conclusion it appears to be related to my machine configuration, and I will research it more. Please don't waste any more of your time with this, as i'm sure you have bigger fish to fry. I am determined to track the cause down, and have started the process of elimination. I will post back here on my findings.
If there's any resources, logs etc which might assist me, please don't hesitate to point me in that direction.
UPDATE: SOLVED
Did a complete reinstall (removed everything from APPDATA and Documents), after exporting only needed profiles. Imported back in and after a quick test shows the issue is gone.
