I just wrote code to do this for my tool popups last night...lucky you!

FindWindow will indeed find only a single instances window.  However, 
why not just do the following:

hwndNext = GetWindow (hwndParent, GW_HWNDFIRST);
while (hwndNext) {
	if ((GetParent(hwndNExt) == hwndParent) &&
	    (GetWindowLong(hwndNext, GWL_STYLE) & WS_POPUP) {
		// yahoo!  land ho!
		GetWindowText (hwndNext, sz, sizeof(sz)-1);
		if (lstrcmp (sz, "title") == 0)
			break;
	}
}

** by the way, I am doing this from the top of my head.  But it looks right!

The code about assumes the window is a popup window.  Thus is is on the same
level as all top level windows in the manager list.

>I will need to know the handles for all windows matching the title I look for

Not with this code you don't.  In fact I have only 10 globals in my program
of over 180k non-debug compiled.  If I can, a Gerbil could.
