Just upgraded from OSX Snow Leopard to Lion.  I use a Logitech Performance MX Mouse.  After the upgrade the OS's interface with the vertical scrolling wheel is inverted.  Instead of scrolling down (or back towards the user) on the wheel and having the browser window (or whatever I'm looking at) scroll down, it scrolls up.  And vis versa (scrolling away from the user on the mouse, scrolls the screen or window down).


Let me know if Logitech issues a firmware update (though I doubt they should have to, as the mouse performed perfectly in 10.6.x).


Hopefully Apple can tweak this soon, as my scrolling is now completely messed up at the office!
