I got a similar impression from the man pages, but those also implied that the singular raise/lower requests would be similarly intercepted. However, they seem to go through fine. As I understand, the primary windows are all children of the root, so they are all siblings, but maybe restack only works on subwindows. In FvwmPager, it seems to be used only for the little mini-windows it owns. Any ideas for an alternative method or a way we can evaluate this further? Is there a way to probe these masks on windows? I don't see it on xprop. -- Jason Weber
