I just received my Logitech G700 for about 2 weeks directly from (sent from U.S. to Middle East) and now click in the middle no longer works. It usually click on a rigid (i guess it was designed like that) now there is no click, as if something just broke inside, it just makes you click the middle button but it does not click as it is supposed do. Spongy pressed with a rare feeling. I think I'll send it back...I am running a Windows XP on my machine.
