Sony Ericsson Bluetooth issue

I was struggling to get my Sony Ericsson Bluetooth to work with my PC. I have the m600i handset. Eventually after searching the complete Internet I discovered by chance the default setting of "power saving" must be off on the handset for it to work. Now it works nicely with the mobile float agent discussed in my previous post. I still think that the SE PC suite leaves a lot to be desired, I have had many a backup that has failed with no greater error message other than something like the handset failed to respond.
