Hi Mike,
There have been some refactoring of the Email class along the way. The class is a bit "old" and was desperate for some love. It's possible (if you have an old build) that the problem has already bee sorted. So grab an up to date build and let me know. (It it hasn't been sorted then email me, and I'll instruct you where to forward the errant mail to, so I can run it through our test system.)
cheers
Bruce
