thanks for asking.

The UIA-10 receiver is an older revision that will probably never be 
supported for legal reasons (I've been able to decode the protocol 
completly, but to make it work would violate Keyspan's copyright as a 
side effect).

The Keyspan Remote for iTunes (URM-15T), though, will work just fine 
with Remote Buddy.

Although you don't experience the problem, but since you mention it:

I've been able to track down the "white box" problem and it will be 
solved with the next release. Basically what the current release is 
doing is to try to open the requester that offers uninstalling the 
Keyspan drivers from the seperate driver thread, which is not 
supported by OS X and yields this as a result. It was merely an 
overlook when going for the multithreaded driver model ;-)

The temporary fix for everybody experiencing this is to just use the 
Uninstall tool supplied by Keyspan directly and only then launch 
Remote Buddy.

Best regards, 
Felix
