I know this seems to be a common problem, but I have yet to find a solution that works.
Our client, http://www.familynameorigins.co.uk/ requires the ability to allow customers to enter the name and a personalised message on the products page.
We have managed to achieve this with the WPEC personalize plugin, which I know is not one of your plugins, but I believe that even if you cannot help, someone who has had this problem before may be able to.
The fields show up fine on the single products page, but when you try to view them in store sales, there is nothing there, the entire user custom fields box has disappeared.
Can anyone help or offer a solution?
