i dont think its your keyclone.

does this only happen with your druid?
are you opening both copies of WoW from the same folder?
try to load with no addons. then slowly add addons to see which ones may be causing the problem. if it just so happens to be your addons, log on with half of your addons loaded. if you get the problem, cut that list by half. if the problem doesnt happen, then you know the addon that's causing the problem is one you havent loaded. eliminate in half again.
