Maybe mucking around in here might help:

"HKLM\Software\Widcomm\BTConfig\"

It's kind of a long shot, but if you're the experimental type...maybe a good way to spend an afternoon with possibly no useful results whatsoever and complete destruction of her BT services (spoken like a guy who's had to hard reset too many times while trying to "discover" things in the registry!). Depends if it's just a low level incompatibility with the Widcomm stack or if it's an issue of settings, of course. Just thought I'd put it out there.
