Can't access objects in dictionary

[Amir Ansari]

OK, that makes sense!  Thanks for clearing this up; I can stop worrying about it now ;-)

Lastly, thank you (and other contributors) for all your time and effort on Magma - I'm using it in a web app, and it's proven to be a simple, elegant system, deserved of a far wider audience...

Happy 2011!

Amir
