SYMPTOMS

When you point to a menu, a submenu may appear after a delay of several seconds. For example, if you click Start, and then point to Programs, the submenu may appear only after several seconds. You may also experience the same behavior if you right-click the desktop, and then point to New.

CAUSE

This behavior may occur if the value for the MenuShowDelay entry in the HKEY_CURRENT_USER\Control Panel\Desktop registry subkey is set to 0. The MenuShowDelay entry does not support the value 0 in Windows Server 2003.

WORKAROUND

Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To work around this behavior, increase the value of the MenuShowDelay registry entry. The MenuShowDelay registry entry controls the time in milliseconds that it takes for a menu to appear when you move your pointer over it. When you set the value of the MenuShowDelay entry, you must make sure that the value is not more than 65536. You may also remove the MenuShowDelay entry from the following registry subkey, and then restart your computer: HKEY_CURRENT_USER\Control Panel\desktop
