Hi, just upgraded from Vista Home to Win7 Home - all went well. But... Using IE8 (and also Firefox) in Vista, my middle mouse button/wheel would open a URL in a new tab. Now in Win7, I get the 'flip' function. I'm sure I never configured my mouse button to do anything in particular when I had Vista - it just used to work and open a new tab. So, in the Win7 control panel I've found multiple options to configure my MS Bluetooth 2.0 mouse middle button... but which option will perform the function of open a new tab ? I know that CTRL-Left Click is the function I want but this can't be mapped to the middle button. Any suggestions ??
