Trevor,
I wouldnt look in the first place at problems of Lilypond. I presume that it
is a problem of Vista which has too many processes running in the
background. You will find, that nearly all programs run slower on this OS.
And even when you only need 10 seconds it is too much compared to what the
processor could manage. You have a machine with much more horsepower under
the hood compared to the "old" systems. And this system performance should
not be consumed by the OS.

Of course a normal user working only with Vista will not notice the
difference. If you have the possibilty to install XP on your laptop I am
sure that you will be astonished what you computer will be able to perform.
We have tried that with different programs on different machines and nearly
always had success.

Hajo
