Mail is deleted unexpectedly from Mailsite Express When deleting messages in MailSite Express, additional messages not selected by the user may also be deleted. This error can occur on Netscape 4.x if the user clicks the browser's built-in 'Back' and 'Forward' navigation buttons when using MailSite Express. After deleting one or more messages from a folder, using the 'Back' button to return to the previous page causes MailSite Express to re-initialize the previous delete operation. Subsequently using 'Forward' to advance to the following page causes MailSite Express to commit the second (unintentional) delete operation, resulting in deleted messages. As with any web application, end users should never navigate through MailSite Express using the browser's navigation buttons.
