I think I ran into this same problem with the beta version.
I reported it, but after a week and a half of constant
effort I finally decided iTools were too advanced for me
and went back to writing programs I could understand.

For what it's worth, I finally concluded this wasn't
possible with the information I was given to work with.
Perhaps you will have better luck. If so, let me know
and I'll write an article.

Cheers,

David
