I'm having a problem with the Logitech Gaming Software (LGS) since many versions now, and am at my wits end. I haven't been able to program my Logitech gaming mouse OR my Logitech gaming keyboard, so I can setup all of these buttons to do whatever I need. I've gone back and forth with the actual Logitech Support, including their highest tech level support, and they ended up not knowing what was wrong!!
