Thanks Martin (and others) for your advice. No, this solution didn't 
quite work either. Well, the extremely annoying thing is that it DOES 
work on another home pc, but on my laptop which I use for work, it 
doesn't want to know!!! Both are running WinXP Pro. All the dependencies 
and paths "seem" to be okay, but there must still be something that I'm 
missing.
