I have notification icons that do not appear at startup or will disappear while computer is in use. Icon behavior for these icons is set to "Show icons and notifications" and this will occur whether or not "Always show all icons and notifications on the taskbar" is checked or not. If I attempt to change icon behavior on a missing icon to "Hide icon and notifications" then change back to "Show icons and notifications", I receive the following message: "This notification icon is not currently active. It will be shown next time it becomes active." Although my system (volume, network, battery) icons are not effected by this, I tried http://support.microsoft.com/default.aspx/kb/945011 which did not work. My OS is Windows 7 Home Premium x64. Any solutions to this issue?
