While running on openwindows ver 2.0 (under olwm, under sunos 4.1.1), I tried
to drag the lobby box from right to left got this:

  sy self

  Do you want to:
     1) Quit Self
     2) Try to print the Self stack
     3) Try to return to the Self prompt
     4) Force a core dump
     5) Loop forever
  Your choice:

I got the same thing doing the same thing when running from the console.  The
problem, I guess, is obvious, but one never knows.
