The latest posting on Codeaholic <http://codeaholic.blogspot.com>
briefly discusses the issue of updating the Windows system tray and
offers a link to UpdateSysTray.DLL, a Delphi COM DLL. This is based on
code published at Experts Exchange and uses system messages to emulate
the passing of the mouse over the system tray, causing it to update.
Kind regards,
