iNotes Web Access - iNotes

On Monday this week, I have noticed that on most Windows XP and a few Windows 98 machines, the display of the Inbox has changed significantly.At the top iNotes Web Access was displayed before, but now it displays just iNotes. The headings are not aligned and the messages only display the senders name and not the subbjet matter. I do not have a clue as to what happened. Although on Windows 2000 the display of the Inbox is fine. Please I need any help that can assist me to rectify this.
