I had previously blogged that I needed to use the Microsoft XP drivers to solve Bluetooth connection issues I was having when I connected/disconnected remotely to my PC via RDP. Well, after I upgraded to v20 on my phone, I found that I could no longer authenticate the phone from my PC using Bluetooth. So, as a long shot, I installed the Bluetooth dongle's software/drivers and voila, it seems to work. I'll keep my fingers crossed that it stays that way. Now if I could only figure out how to get protected WMAs to work…
