Hi, how do you embed xterm? I didn't know xterm supported Xembed (but it

Why not? MapNotify is a badic function of the X protocol - if scrotwm
override-redirects embedded windows and keeps vital events from them, then
it's broken.

If rxvt-unicode calls mapwindow, and the wm makes it visible, then
rxvt-unicode is entitled to know about that.
