fix CONFIG not working if nothing changed and got less flickering by separating text output (#1034) 
-fix CONFIG dysfunction if nothing had changed: this was a reminiscence of the nothread conversion
-addressed screen flickering: reduced it by separating two text output
-variables: took out unneeded userpause (reminiscence of the nothread conversion)
-solved problem with manual range not updating description on consecutive clicks
-solved problem with direction changing on 'UNLOCK/SKIPLCK'
