uploading code to arduino BT

Hi,
I've been having problems uploading my code from the arduino IDE to the Arduino BT microcontroller. I'm using the Bluetooth USB Dongle KB018 (BlueSoleil), which may be the problem, since I was able to successfully upload my codes with another usb adaptor. Unfortunately I lost that one, and did not have any documentation about its drivers (WIDCOMM or BlueSoleil?...). :-[

Anyway, with the BlueSoleil Adaptor, I'm able to form the connection between microcontroller and PC. BUT whenever I try to upload code, it always disconnects!

Could someone let me know what USB bluetooth dongles are compatible for uploading programs onto the arduino BT?

Thanks!
