Hi bisenberger.

Thanks for the info.

I have read the web article and, for the time being, I don't change my mind.

Nevercenter says :
"...Under-the-hood rewrites (to improve performance and stability)
Bug fixes..."

Well, what can I say ? ... a little bit vague and unsatisfying.

Silo could do with a very deep and strong rewrite for almost all its aspects, above all its inadequate stability.

Anyway, thanks again for sharing.
