You could use SendKeys.Send("{ESC}"); in the trigger event when the user clicks somewhere else.

There is no lost focus event for context menu, so I added it at mouse leave event. If I use send keys function, it also closes the message box. so user is unable to see the message box. – Sharique Feb 01 '11 at 11:49
Yeah, this is very bad solution for a number of reasons. You've already seen two of them. – Cody Gray - on strike Feb 01 '11 at 11:56

That's a bug. Probably in Windows, the MSDN Library documentation for TrackPopupMenu documents a very similar problem. I don't see an obvious workaround, other than avoiding using MessageBox. Create a little form to be your About box. Display it with the Show() method.
