in the same place you got cotobo is a forum, where most people prefer to have posts about it. I thought, since no one else mentioned it id be the one :P Since im in a contrary mood.
ya, try disabling those things. If theyre not activated make sure ur ctrl or T button isnt stuck or being pushed down. (Maybe spilt coke on it) Or else look for the newest version of CoTobo...Or dun use it, OR delete it and reinstall...Yeah :P
