Hi Mike,

I have yes. That shouldn't be the issue.
Actually I had  already been searching for an app that does XHR
succesfully, just hadnt found it yet. I will dive into your code and now
I'm sure I will spot where I'm going wrong :)

I was starting to doubt it could be done at all.


cheers!

Mathijs
