Couple weeks ago, my G500 started acting weird. When I made a single left click, it sometimes resulted in a double click. After a while it became very frequent and annoying...

I tried that solution today : http://zalbee.intricus.net/2014/02/how-i-fixe...500-mouse/

It wasn't too easy to put the spring back into the switch after a little cleaning, but that's really doable quickly with a little luck :)

I'll see how it goes.

Anyone with the same bug who managed to fix it ?
