I get that message all the time as well.. I use my laptop & touch pad when fighting.. it seems to be faster than using the mouse on bosses.. so yes, I can see where the server & browser is trying to catch up with fast clicks..
i dont think thats gonna happen.if that were the case i already woulda been flagged as i get the message ALOT.
last week i was "auto" suspended for 4miutes as i was mistakenly flagged for bot play, so it can and does happen.
