Vista - Bluetooth connects then immediately disconnects

I have an HP DV9610 with Bluetooth and a Palm 700wx also with Bluetooth. When
I set up a pairing Vista finds the phone immediatley and the pairing goes
smoothly. As soon as it's done, in the Bluetooth Devices applet it says
connected then
immediately disconnects. This is repeatable. Whenever I go into the phone's
Bluetooth properties in the Bluetooth Devices app and exit , it connects then
disconnects. I have Windows Mobile Device center 6.1

I had Mobile Device center 6.0, but it wouldn't find the (WM5) phone even
via USB. I installed 6.1 and the USB sync now works fine. I am trying to set
up the Bluetooth sync and a Bluetooh connection in general. With 6.0 I could
connect with the phone (storage card) but not sync. The connection was stable
and I could browse the phones storage, but now nothing at all with 6.1.

I found a post suggesting I turn of UAC but that didn't do anything.
