Fixing SLED (Suse/OpenSUSE) and the middle mouse button behavior
In case anyone else runs into this, if you are using any derivative of Suse and you can't seem to get your middle mouse button click and drag to work (that would be MB2 drag), you might be encountering the same issue that I did. I couldn't drag with the middle button at all until I realized that there was a mouse setting in the YaST mouse configuration that made my middle mouse button work like a Wheel Mouse. If you're running the proprietary ATI drivers like I am, you won't be able to edit it directly from the Mouse config, but you can go into the xorg.conf file and make it happen. Just remove the line that talks about the mouse wheel button stuff.
