Thank you very much, salt-summer.
That is the worst problem: something hard to reproduce, adding another layer of complexity.
Since everyone is worldwide, the one I needed to answer is 8 hours ahead of my time (Pacific Time), meaning he is out of the office already. Sorry about that.
I hope to get something useful to share.
Any product is only as good as its support, which is my personal "credo". I hope my little push will help. Fingers crossed.
Thanks again!
