I'm in the process of trying to get going with LyX again after a year's 
lack of use.  I have a few problems:

1. The last document I wrote made two references to the same footnote.
   I used the LaTeX font to surround a LyX reference to the footnote
   with "\footnotemark[" on one side and "]" on the other.  LaTeX
   doesn't seem to like LyX's output for that anymore.  The error box
   says

                Missing number, treated as zero.
                ...\_host\_key\footnotemark[\ref{foot:etc}]

                A number should have been here; I inserted '0'.
                (If you can't figure out why I needed to see an number,
                look up `wienr error' in the index to The TeXbook.)

2. When I ask to view a landscape (FoilTeX) image in DVI, Xdvi displays
   the landscape mode slide with a portrait mode page outline
   superimposed upon it, even though LyX's Layout --> Document ... -->
   Paper Orientation is set to Landscape (and Letter).

3. How PDF output is generally unacceptable, and its detailed
   appearence seems to depend upon which PDF option I first select from
   the View menu.

   a. If I first choose "PDF (pdflatex)" then the full screen acroread
      display comes out aparently in A3 proportions and portrait
      orientation, in spite of my selections of letter and landscape
      within LyX.  Stuff gets cut off and EPS graphics don't get
      rendered at all.

      If instead I choose either of the other two PDF engines first,
      I get their output instead when I later choose "PDF (pdflatex)".

   b. If I choose "PDF (dvipdfm)" then the full screen acroread
      display comes out in landscape mode and letter proportions
      alright, and EPS graphics are displayed (if somewhat roughly),
      but all text areas on pages containing any EPS graphics are
      rendered with dark gray text against a black background.  The
      backgrounds of second and succeeding EPS graphics on a page
      are also black.

      If toolbars, etc. are displayed as well, instead of using full
      screen display, rendering of both text and EPS graphics is
      normal, though the graphics are still rough.

   c. If I first choose "PDF" then the full screen acroread display
      looks much like b), above, except the text areas are black on
      black instead of dark gray on black.

      Again, less than full screen display is normal, though the EPS
      is rough.

4. EPS graphics and text fonts are crisp and beautiful and displayed
   with the proper propostions and orientation when displayed in gv,
   but it doesn't seem to have any way of doing a full-screen display.

The upshot of 2, 3, and 4, above, is that there no longer seems to be any 
way, much less a good looking way, to drive a projector with a laptop full 
screen display.

The specifications:

        IBM T23 ThinkPad
        FreeBSD 4.9-STABLE
        LyX 1.3.3
        Xforms 1.0_3,1
        Acroread 5.08
        teTeX 2.0.2_2

All applications software is the latest from the FreeBSD Ports collection.

Can anyone help me make sense of this?  I have two more days before I have 
to demo LyX to a sceptical crowd of Unix/Linux, Windows, and MacOS X users 
to pursuade them that we should use it to develop a set of long-lived 
documents.

Thanks for your efforts.
