Description
Contrary to what Windows does, ReactOS emits a WM_RBUTTONUP message when you right-click on the title-bar of an application, and before sending the WM_CONTEXTMENU message, so that, if you internally deal with WM_RBUTTONUP and you don't let afterwards the default Window Procedure dealing with this message, you never get the title-bar context menu, aka. the window system menu.
Windows :
========
- Right-click on the title-bar
- WM_NBUTTONDOWN
- WM_CONTEXTMENU
ReactOS :
========
- Right-click on the title-bar
- WM_NBUTTONDOWN ?
- WM_RBUTTONUP
-WM_CONTEXTMENU
