//	of the material editor pane.
//	To override this, we subclass each dialog so that we can capture the mouse
//	messages before MAX processes them and then reroute them appropriately.
//	Note: because MAX already uses the window long of the given window, we can't
//	store the old proc of the window. However, since we always use 
//	CreateChildCPParamMap2, and because the MAX source code shows us that it
//	always uses the same dialog proc for all windows created with that function,
//	we can simply store the address of that proc the first time we subclass and
//	use it for restoring every time thereafter (see the following DlgProc)
