There seems to be a bug where you cannot use left, right, up or down arrow keys in the compose area of messages if you have the iMessage window on a 2nd monitor.  I believe this bug goes back to one of the betas. Does anyone have a fix for it other than waiting for an update from Apple?  Already submitted feedback. 
Thanks!
