IIUC, the problem was this:

note_mouse_movement is used to handle mouse movement event when
track-mouse is not active, but last_mouse_glyph is only updated when
track-mouse is active.

So it was wrong (or at least stupid) for note_mouse_movement to test
on last_mouse_glyph which would have an arbitrary value based on where
you clicked/dragged the mouse the last time.

Chong, perhaps you can try to understand why you have problems with
mouse clicks due to this change.  I don't have the reported problem,
so I cannot debug it.

Do you have some hacks in mouse.el which may cause problems?
