I'm a little puzzled on two points in MS Windows, perhaps someone
out there could help me.

1.	I am a little unsure on the differences between: InvalidateRect()
	and UpdateWindow().  Are the following equivalent or not:

	InvalidateRect(hwnd, NULL, TRUE);

	UpdateWindow(hwnd);

	If these are functionally the same, which is preferred and why?

2.	Regarding timers... I can set one timer fine, but when I try to
	create more than one (i.e, two !) the first one doesn't seem to
	work anymore.  Is there something fundamental that I've missed?


Thanks all,

Frank
