There's a couple of forked versions of xdvi isn't there? Perhaps
someone has attacked this already.
For what it's worth I looked briefly at what might be going on and it
seems the button widgets etc are created at startup correctly, but the
main viewport is sized to the full top-level window size, so the
buttons are hidden away to the right (but resizing the top-level
doesn't help, I think the Form widget chaining might keep them in the
same positions relative to the right edge). Pressing "x" twice
destroys and re-creates the buttons and in the process recalculates
the size for the viewport.
I'm not quite sure what's wrong in the startup case. Presumably the
initial size calculations no longer work on unrealized widgets, or
something like that. I don't know if xdvi is doing the wrong thing or
if something is broken in Xaw.
