I have an application that I want to run in the background.

It has a small loop that executes upon null events that starts with
FrontWindow(), and performs a procedure based upon the windowKind and
refCon fields of each window, until it hits the end of the window list.

this is the code:
WindowPeek v, w = FrontWindow();
while (w != nil) {
	v = w->nextwindow; /*the next call could get rid of w*/
	/*the call is here*/
	w = v;
	}

It runs fine in the foreground, but I think the problem is this:

Each application/layer has its own list of windows, ending in null.
FrontWindow() returns the front window of the *TOP* layer, not the
 calling layer.

I cant grab the front window on suspend, as the calling loop may
dispose of it.  What I need is a way to get the front window of my
layer while it is in the background.  I might be missing something
really stupid, as I am currently wired and tired.

If anybody has any ideas, please send me them, it would be most appreciated.
