Only 5000 places for Pi, Ferren? There's a bloke in England can 
remember (no, not calculate) it to 20,000 places, so if you want to 
test him you'll have to do better!  ;-)

In passing it to Foo, the question would be: Was Foo actually there? ;-)

In respect of Snow Leopard -- everyone should take Brian's advice and 
upgrade to it. Here's why: X.6.3 is what OS X is actually supposed to 
be.

Here's how I know: Canvas X, written to OS X carbon specs, was full 
of bugs. Under OS X.6.3 it now runs practically bug-free despite 
nothing having been changed in Canvas X for about 5 years because it 
is no longer supported for Mac. Runs in Rosetta, of course. Clearly, 
all those "Canvas X bugs" we used to complain about were actually OS 
X bugs.

In fact, Apple virtually admits this saying OS X.6.x is the great 
clean-up and stuff.

I bet the next version of NWP will be faster and whatnot because 
compromises they had to put in to accommodate Apple's buggy OS can 
now be eliminated.

On the other hand, the people at VM Fusion used to have a video up 
explain about OS X -- and saying that far from being a pure, 
purpose-built OS, it was a lash up of odds, sods and bits from the 
leftovers bowl at the back of the fridge.

And, of course, we should bear in mind that Apple doesn't use its own 
OS X text engine in Pages -- they gave it its own text engine. That 
should tell us something.

Cheers, Geoff
