I just installed an MSI bluetooth 2.0 dongle for my PowerMac and file transfers with my phone work perfectly fine under Tiger (although headsets do not work). Headsets work fine under Leopard, but for the life of me I cannot get Leopard to transfer files from the phone or even my PC (which again worked fine under Tiger). I've searched online and the common response is to make sure Bluetooth Sharing is turned on in the Sharing Preference widget (well it IS turned on) and Bluetooth File Transfer is also turned on in the Firewall application setting. I also tried turning off the Firewall. Still no joy. The thing simply refuses to transfer files. It just sits there. Similarly, I've had issues getting Yahoo Messenger 3.0 Beta 3 to connect unless I use the firewall setting (which hints that it IS a firewall issue). I added Yahoo Messenger to the application list and it worked the next time I launched it, but then the time after that it wouldn't start again. It seems as if Leopard is simply ignoring user Firewall settings, be they all on/off or individual app selections. This is beyond frustrating. I want to start moving over to Leopard on a semi-permanent basis, but if major functions don't work, I simply cannot do it. If anyone has any suggestions, let me know. Thanks.
