I have also noted one bug and one omission in Smalltalk/V Mac (a product
which I heartily enjoy :-)):

   1. Horizontal scrollbars don't scroll "by screens" correctly.  By
      "by screens", I mean clicking to the right of the bubble, on the gray
      area, which should scroll in screen-sized chunks (the same for the
      vertical scrollbar).  But if you generate something huge (such as
      250 factorial), the page scrolling works twice, then you are forced to 
      scroll with the arrow only.  Dragging the bubble all the way to the
      right does not work, either.  The only way to see the whole line is to
      use the scroll arrow--a slow proposition.

   2. Is there any provision for a stream to/from the Serial port?  I searched
      all through Inside Mac, and basically decided--am I right?--that the I/O
      calls that are documented are not direct Trap calls.  Therefore, I would
      have to go to Lightspeed C and write a VPRM to do i/o.  It is great that
      Smalltalk/V has this nice hook, but it would be nice to have serial
      i/o capability primitives supplied.  Or did I just miss something?
