But Vista is very pretty :)

Not relevant to the immediate problem, but the 
de-install left three files behind:

LilyPond/usr/bin/lily-pad-unicode.exe
LilyPond/usr/share/lilypond/current/dvips/ps/lilyponddefs.ps
LilyPond/usr/share/lilypond/current/dvips/ps/music-drawing-routines.ps

as well as the three files in the font cache.

I left these untouched and re-installed:

The first run accessed just the two smaller files
in the font cache, but still completed in less
than 5 secs.  Subsequent runs less than 3 secs on
trivial files.

Exactly the same - all short compile times.

I de-installed again, this time deleting the
font cache, and re-installed without admin rights.
Now the first run takes c 1 min while it rebuilds
the font cache, but subsequent runs are the usual
3 sec.  The font cache was rebuilt in exactly the 
same place.

Tried running as a different user, one without
any priviledges and no admin rights.  As expected,
the first run took 50 secs to build the cache for
this user - in [user]/.lilypond-fonts.cache-2 -
but subsequent runs took the usual 3 secs.

It seems my Vista runs LilyPond 2.11.42 perfectly.
I can't make it run slowly.  So we need to find a 
user with the problem to make any further progress.

Perhaps worth mentioning - my OS is Vista Home
Premium, fully patched up to today.

Is it possible to find out the differences between
the three versions of libfontconfig-1.dll?  Might
this may have been upgraded for Vista, since the
later version fails on XP but works fine on Vista,
as the above demonstrates?
