Version: Left Mouse Button Fix 1.0
Easy installation (not even a restart required, just open the executable and it's fixed), fixed a problem I've been having for *years* with my Razer Deathadder (unsure what year).
As the other guy said, unfortunately it's a problem you either need to boot manually each restart, or add to your startup programs. Still, it's a relatively lightweight program (6000k in resource monitor) and does keep a nice little running tally of fixed double clicks. Still gets 5 stars from me.
