I installed version 2.11.43-2 and had exactly the same problem as 
before.  I suppose I uninstalled the previous copy correctly, but it's 
been several years since I used Windows regularly and don't really know 
much about how it works.  I used the add/remove programs feature of the 
control panel, chose Lilypond, and clicked "uninstall."  The uninstaller 
ran (took a really long time--is this normal?  Like 3-4 minutes, whereas 
on Linux it's about one second) and it said it was successful.  Before I 
ran the uninstaller I deleted the cache files from the 2.11.63-1 
installation.

While Vista does run much slower in general than my Linux machines, I 
don't think it's the OS slowing Lilypond down in this case.  I'm pretty 
sure there's no virus problems either since I hardly ever connect to the 
net while on Windows.  The fontconfig cache file is definitely being 
modified each time (rebuilt, I suppose) because the time/date stamp on 
it changes every time I run a .ly file.  I suspect this is the problem 
but have no idea what to do about it.  Is there anything else I should try?

p.s. BTW Lilypond also runs kind of slow on my Macs, but not nearly as 
slow as on Vista.  It's not slow enough where I'd think there was any 
real problem.
