My Proteus Spectrum is developing this. Its early stage so its not unusable yet, but when it does get bad enough I was looking into getting a Glaive to compliment by K70 LUX RGB (my pride and joy peripheral). So I was saddened to see that a double-click issue was very prevalent early into ownership for a lot of users. If it is actually a FW issue and not faulty switches, I'll be much more comfortable jumping on board once my current mouse tanks.
Unless of course the tutuorial above would fix my current mouse. I always knew of the procedure but most called on removing the plate entirely, at which point I could never, EVER get it back on. If the toothpick method works without outright removal, that'd be cool.
But I do have a hankerin' for the Glaive either way... :)
