Looks like it is the similar problem I have but with vista. Crossing fingers hoping some one from Arduino would look into this issue and fix or suggest a patch or solution.

Yes paired. Link is up when opening serial monitor. Able to download blink sketch. However no luck in making serial comm working. Thanks

Hello Firneds
HW Set up: Arduino BT board(Atmega 328); Computer has USB BT dongle;
SW set up: Arduino 1.0.3, Win vista;
Programming mode checked: AVRISP Mk2; Baud 9600;
Even for the following simple code the serial monitor does not give any out put. I try including <SoftwareSerial.h> and no luck.
Any suggestions please?

Code:

void setup() {
    Serial.begin(9600); // opens serial port, sets data rate to 9600 bps
    Serial.println("Hello Computer");
}

void loop() {

  Serial.println("Hello Computer");

}
