Very remiss (and rude) of me not to reply before now - apologies for
that.

@Markw65
Thanks for that. It's an error I've made before, and I'm sure I will
again although I'll try not to. Made the changes you suggested and can
now get rid of the alert message. I decided to go further and remove
the whole Initialise step and incorporate it all in the page load.
(The Linestring and Model can still be changed but now have to be done
within the Set_Defaults function as I wanted to make the next version
less generic and simplify it a bit).

@Tanguy
Thanks for the ideas :)
I tried the Speedo Gauge but found that unless I set it to update
every 1second, say, rather than every tick it really slowed everything
down. Looked at using the Bindows gauges instead which looked
promising to begin with as they only redraw the arrow rather than the
whole control but I gather they don't work on Safari and I didn't want
to restrict myself at this stage.
Still looking though - but for now I'll just leave the speedo as a
text field - open to suggestions though.

I've found some time to play around a bit more and have added a
circuit overview in a map div and tidied things up a bit. The latest
copy can be found at

Some issues still remain however which I'd like to sort out if anyone
can point me in the right direction.

The main one is the issue of what happens if when you're really close
to the car and Pause the tour. This is especially apparent when using
LookAt.

If I'm running the tour and zoom in to between 4 or 5 metres, say, and
then Pause the view changes to be looking down on the car. If I then
restart it goes back to where it was. Don't know what's causing this
but any assistance would be greatly appreciated - I promise to
acknowledge replies in a more timely fashion this time ;)

Thanks in advance
