: Does anybody know a way to make an obscurred window
: rise to the top?
:
: or to "always" stay on top?

Well, in general, you don't want to do this because you are fighting
with the window manager.

However, if you want to pick that fight, here's how :-)  Basically,
you put a visibility notify on the outside X window, and when it
becomes obscured, you raise that window.  This is from a program I
wrote where 'top' is an override redirect window (think toolbar menu),
but it should work with non-override redirect windows as well.

void
raise_me( const XEvent *ep, void *argp )
{
	if (ep->xany.type == VisibilityNotify && ep->xvisibility.state != VisibilityUnobscured)
		XRaiseWindow( ((OI_d_tech *) argp)->display(), ((OI_d_tech *)argp)->outside_X_window());
}

int
main( int argc, char ** argv )
{
// ...
	top = oi_create_box( "top", 1, 1 );
	cp->dispatch_insert( top->outside_X_window(), VisibilityNotify, VisibilityChangeMask, &raise_me, (void *) top );
// ...
}
