Heya,
I am posting this for people who might be having trouble with certain BS keyboard mapping(s) not working on their notebook computer.
My system is an HP HDX Dragon with the 20.1" display. It is a full blown luggable Vista 64 Media Center complete with all the trimmings including an infrared remote control and therein lies the problem.
The infrared receiver on the HDX uses the ITECIR driver which is common on a lot of notebooks these days. It has been known to cause problems in other games like Fallout 3 where the tilde key won't bring up the console. In DCS: BS the backslash key won't bring up the communication menu. There might be other key issues, but I am still learning BS and have really only scratched the surface.
So, if you are experiencing these kinds of problem with DCS or or other games on your notebook, this might work for you as well:
Open up Device Manger, expand the Human Interfaces section, and disable the ITECIR driver (if you can).
On my system, disable is grayed out so I have to uninstall the ITECIR driver (without checking delete drivers) and let the system re-detect it on the next re-start or manual hardware scan.
Yup, it's a pain the arse, but the HDX Dragon is a rocking notebook and I wouldn't trade it for even fastest i7 system--at least not yet.
I hope this helps somebody.
