Thanks for the reply. Mine does work in Microsoft Apps, but not in the others. Unfortunately OS X's mouse support, like OS 9 leaves a lot to be desired. With USB overdrive, the scroll worked in everything, and I could set up button 3 & 4 to go forward & backward in applications that it was usefull for.
If anyone has any ideas or has found a third party software supplier, please yell out
I use an Intellimouse and it works quite well. The right button has a contextual menu for almost all the aps I use and in the Dock. The wheel works in IE and in apps like TextEdit abd BBEdit, and may others. It does not, however, work in the finder...so I hope they add that to 10.1.
I hope apple start to make a 2 button + wheel in the future, since it seems to be natively supported on OS X
