This SetForegroundWindow() and PostMessage( , APPWM_NOP, , ) are
recommended in some MSDN sample code; apparently there's a bug in most if
not all versions of Windows: Tray icon menus don't vanish properly when
cancelled unless you provide special coddling.
In MSDN, see: "PRB: Menus for Notification Icons Don't Work Correctly",
Q135788:
mk:@ivt:kb/Source/win32sdk/q135788.htm
Example code:
mk:@ivt:pdref/good/code/graphics/gdi/setdisp/c3447_7lbt.htm
Both of these pseudo-URL's are from the July 1998 MSDN. Those geniuses
have since completely re-broken MSDN at least once, so the pseudo-URL's
are useless with more recent MSDN's.
In the April 2000 MSDN, you can search titles for "Menus for
Notification Icons"; "Don't" in the title has been changed to "Do Not",
and searching for either complete title doesn't work anyway. Good old
MSDN.
