If you type Michael's code in there, it prints "Starting" but the font size never changes (note: the "root" referenced in Michael's code is the same as "canvas" in dlrconsole, so simply do "root = canvas" before typing in the code ... and sorry that there's no copy/paste! I guess that should be fixed =P)

I'm actually using the binaries that Dino gave me - which if anything 
should be more up to date than the ones from dynamicsilverlight.net. 
Perhaps it is something to do with the environment as I was testing it 
in my 'webide' which is a fairly similar environment to the DLRConsole. 
I've just got into London and will try it as a standalone script when I 
get home.

Thanks for trying this for me - and great to meet you Harry.
