Activesync - "Disconnect when done" not working

[admisi]

Wonder if anyone can help here. I never use my Jam with the USB, and I have Activesync setup for Bluetooth. When I connect via Bluetooth, everything works great and phone syncs. But it won't disconnect when done syncing and I sometimes forget to, which eats battery life.

There is an option in Activesync on the phone..Tools, Options, Options, Disconnect when done, which I have checked of course, but still no joy.

Anybody got a solution?
( I just want it to Connect via Bluetooth, synchronise with Activesync, and then disconnect)

Thanks
