When all entries are filled on one particular form sheet, users must press the ''Commit'' button - this will transfer the information to the working memory. Failure to ''Commit'' information before exiting a page, or just resizing the viewer, will cause the loss of all the information entered. If this is the case (at least) all mandatory fields (flagged with a red asterisk) must be filled in again. It is also recommended NOT to use the ''Back'' and ''Forward'' button of the browser to navigate to the different pages.
