I have tried 3 different mice on 2 different computers. All 3 mice are plug and play, that is to say you don't have to install the drivers for them to function as Windows 7 recognises them as pointing devices. Until installing Type I hadn't noticed them being a problem.
The Microsoft mousewheels only work when the Microsoft intellipoint software is installed. I do not normally have the intellipoint software installed as it is less smooth in some programs and can cause problems. I noticed the Wireless mouse was not particularly smooth scrolling after installing intellipoint, this problem was evident in other programs too.
I'm probably not the only MS mouse user to avoid using the infernal intellipoint.
The Logitech mousewheel works correctly, Zooms in & out, with the default Windows drivers and the Logitech driver software.
