Gnome 64-bit DVD; Middle click scrolling did not work until I changed that bool.
Without that bool on I can't hold my middle mouse button to scroll(any mouse) and all of my ThinkPads' Trackpoints have middle buttons which are intended for scrolling. By default in most Linux distros middle click only acts as paste.
Also, LibreOffice 3.3 Final is out now, it's a stable release.
Don't understand the mouse bit, Firefox has always worked straight from install for scroll mouse ever since it first came out for me, but checked out LibreOffice web site and followed their instructions and installed LibreOffice in about 10 minutes and it all works fine. I expect Mint will have a repo for it later so will add that if/when it exists and it will all be kept upto date from then on I expect
