An update.
I have install a fresh version of zen-cart in a sub folder.
I had no problem making an order. Perfect.
So, the two difference were :
1) Clean install
2) No SSL at checkout.
I decided to try a NO SSL checkout with my current setup.
Bingo. Order was process perfect, even the refund were posted in zen-cart admin once issued.
Any idea how to solve this ? I really need my SSL, as a few client manifested the desire for it, when I ddint have it.
Thanks
