A little over a year ago I bought a RK-9000 (cherry blues) from ChiefValue. About a month ago it started to type certain keys twice after only one press. It does it now multiple times per sentence and is really annoying/time consuming to correct all the time. Tried removing the keycaps of the offending keys and re-seating them, cleaning out with compressed air (was clean to begin with - no spills/dust buildup) but nothing works. Any idea how to fix this or do I need to buy a new KB? CV already said hey will RMA with a full refund, but I'd much rather keep this than buy a new mechanical kb. Any ideas appreciated!!
