A word processor document has inserted mail merge fields.
When you select a dataset in the attached database and push the button "data to
fields" the values are inserted in the document.
When you now print, all works fine.
But if you deselect the dataset, or close the database view, or you reopen a
document, printing results in a loss of the values.

In StarOffice 5.2 this behaviour doesn' t appear.

This is a important function. We use SO 5.1 in our company. We have templates
for Telefax, letter an so on, where mail merge fields are used to build the
address field. So a address is easily set throw get the dataset and push "data
to fields".
