Correct. Just as if you had told xterm to appear at 0x0, and Firefox to appear at 0x0, they all appear at 0x0, because that is where you are telling them to appear. Those co-ordinates are absolute, not relative. The new window will be obscured by the panel because the panel is probably set to the top X layer. You could try setting the new window's layer element in rc.xml, see if that overrides the panel.

That's right, because that's where you are telling them to appear. What you really want to tell them is to open at 0x32, for example. The margin element is for windows that open according to the placement element. Telling a window to open at a particular position overrides that.

They do; you just think they're something that they're not.
