K800i bluetooth using dongle - image push starts but xfer's 0 bytes

Hi,

I cannot get bluetooth data xfers (jpg's) working between my K800i and
my PC.

The phone see's the PC, the PC see's the phone, they are paired, when
trying to bluetooth images from phone to PC the process starts and the
PC apps (supplied with dongle and not the SE suite) show something
starts, but it stops with about 300 bytes sent and 49 bytes received.
The phone shows 0/839KB xferred and goes no further.

Trying to connect via bluetooth using the SE suite never see's any
devices!

I thought bluetooth would be a sinch - it seems totally awful. Anyone
know what is wrong? Searching google finds no help.

Thanks.
