When a user clicks on a balloon created by the Framework's NotifyIcon
class there seems no way to tell the difference between a user clicking
on the X close button and clicking anywhere on the balloon.
When the user clicks on the X close button no click event is generated.
Only the BalloonTipClosed event.
Unfortunately, when the OS times out the balloon the only event that
fires is that same BalloonTipClosed even.  Therefore, it seems
impossible to tell if the user clicked the X button to hide the balloon
or the OS closed it.
The object here is to redisplay the balloon until the user clicks on
the balloon.

Does anyone know what can be done?

Thanks in advance.
