Disappearing systray icon fix

[Roger Garstang]

Never have any disappear myself...are you talking about in general or like when Explorer crashes and they all go away then some come back with others missing? If it is the later, you can use RegisterWindowMessage("TaskbarCreated") in your apps to detect when the bar comes back and recreate your icons.

Some icons on the systray disappear using XP SP3.

Logging off then back on would bring them back.
