[PVS-Help] Not at a formula declaration

[Jerome <jerome@xxxxxxxxxxxxxx>]

I put my cursor over a lemma, type 'M-x prove', and get the following
error in the status buffer: "Not at a formula declaration." I've done
this several times in the past (even successfully to the file in
question), so I'm quite certain my cursor is over a forumla. What
makes this even stranger is that it only happens in two of three files
in my working directory.

It looks like BUG 926 addresses this issue, but I can't seem to get
the webpage to load.
