As far as I can tell, it attaches the TrackMouseEvent stuff to the window on any mouse move (but I guess the underlying win32 system only attaches one actual event.) When the WM_LEAVE is sent, then the next move attaches a new one... But it seems like, in the GL window, the WM_LEAVE is sent pretty much as soon as it is attached, or something, and the next mouse-move attaches another, causing a flood of WM_LEAVE messages whenever the mouse moves... I have no idea why this happens, but I guess that Matthias' suggestion that the hWnd is wrong might make some sense - we maybe have the hWnd for the main window rather than the GL window, or vice-versa...? Anyway, *not* doing the TrackMouseEvent stuff seems to make this all work OK in a GL window, and as far as I can see the subwindow enter/leave stuff still works (well, the test/subwindow demo still seems to work, anyway) so I am not sure what functionality we lose? I don't understand enough about this mechanism to know...
