That's because you're asking for events on canvas, not the paint window.
Change you're code to include something like the following:

                ...
		CANVAS_PAINTWINDOW_ATTRS,
			WIN_CONSUME_EVENTS,
				WIN_MOUSE_BUTTONS,
				LOC_DRAG,
				LOC_MOVE,
				LOC_WINEXIT,
				NULL,
			WIN_EVENT_PROC, CB_Canvas,
			NULL,
                        ...

>	                        CANVAS_WIDTH         ,XFP_IMAGE_WIDTH,
