small button patch

[Rein Klazes <rklazes@xs4all.nl>]

hi,

Application does a SetCapture() when the mousepointer is moved above a
button. In this case the button should NOT change state, unless the
mouse button is pressed.  Verified under Win2000.

	controls/		: button.c
	Don't change button state on WM_MOUSEMOVE messages unless left
	mouse button is pressed.

Rein.
