If you are thinking of buying a bluetooth dongle for your computer. Either make sure you go for a brand name like linksys or belkin. Or ensure that it DOES NOT  have the "BLUESOLEIL" software with it.

I have recently purchased 3 dongle all with the bluesoleil software. & i had nothing but trouble getting files to & from my mobile phone, Other PC's & my PDA.
The first one i bought, that was not bluesoleil related works fine. Sending files to any other PC, (even next door) PDA or mobile fones is very easy. Simply a matter of right clicking the file to send. Click send to, bluetooth device selecting the device that i want to send it to. Then OK and away it goes.

If you thinking of buying one from ebay, just ask the seller first if it has the bluesoleil software with it. If the answers yes, i would steer well away from it.
