Glad you got that to work. I was thinking (an unreliable task for me, but hey, why not). I have a long USB extension cable that came with a dongle like the one you have. I wonder what would happen if you used something like this, and moved the dongle away from your rig.
Hmmm, interesting thought. If (when) it happens again, I'll try that. But, as of right now, the BT connection is good.
Thanks
