I still believe it is a problem with screen.  The fact remains that
screen sits between slang and the physical terminal and, as far as I
know, presents the same abstract terminal to slang regardless of the
underlying physical terminal.  Pictorially, here is the situation as I
see it:

 SLANG --(screen-specific-escape sequences)-->  
          SCREEN --(mlterm-specific escape seqences)--> MLTERM

 SLANG --(screen-specific-escape sequences)-->  
          SCREEN --(xterm-specific escape seqences)--> XTERM

You reported that slang+screen works properly for xterm but fails for
mlterm.  I do not understand how slang can be responsible for this
behavior since the escape sequences it sends to screen do not change.
To test this hypothesis, please try this:

   In mlterm do:  
   
      script /tmp/mlterm.log
      /path/to/your/slsmg/code
        (press the keys to produce the problem, then quit)
      exit
      
   In xterm, do:

      script /tmp/xterm.log
      /path/to/your/slsmg/code
        (press the EXACT same keys as above, then quit)
      exit
      
Then send me xterm.log and mlterm.log.
Thanks,
