When you actually clic a mouse, there's a flurry of lower level
messages, (WM_NC... and friends), which you're not fully
reproducing here (and are pretty hard to reproduce!).  That's
why Win32, to allow simulating mouse-clics, provides the
SendInput API (in NT4 SP4, and Win98, and later; there was
a mouse_event API in older versions, but I'm not sue if it
works well with modern platforms).  Not sure if win32api
covers it, though.
