The easiest way to do this is to open the smaller window as a modal
dialog from the larger one. That way you won't be fighting the window
manager all the time. Note that this will probably only work for mwm:
it probably won't work with twm and olwm (and its variants) because
they are broken WRT modal dialogs (among other things ;-)

One other possible techique is checking "the openStacks" in an idle
handler and using "go" to bring a stack back to the top.

Set the button's traversalOn property to false to fix this problem.
