question about a bluetooth mouse

Hi Folks

I have a Sony Vaio VGNFW140 with built in bluetooth and a M$ bluetooth mouse I bought separately. It works fine other than it was a little difficult to get it to pair with the laptop. I have one problem, I’m playing with Blender and pressing the scrollwheel and dragging should orbit the view. This doesn’t work. it works with a usb mouse and it works with a wireless mouse that has one of those usb antennas. Just not the built in bluetooth.
oh yea, in Okular I can press the scrollwheel and drag and it zooms the document so it’s recognizing the pressing of the scrollwheel

So, question: how do those mice with the usb antennas work?
Are they bluetooth?
Or do they use their own wireless protocol
just trying to figure out whats going on

The wireless ones with the usb plugs/aerials don’t use bluetooth, they use ta regular wireless channel.
