I Also read that KWin wouldn't support this, the KDE guys thinks it the wrong way to go. -- //Aho E-Mail: tr...@iname.com URL: http://www.kotiaho.net/ ICQ: 13696780 Skype: jo_aho System: Linux System(PPC7447/1000 AMD K8/2500) EU forbids you to send spam without my permission

Might give a hint of where it came from. xterm returns to working. But restarting ctwm, doesn't return this property. So perhaps I was wrong, and ctwm isn't at all the one which adds this wrong property for me? It appears (?) that ctwm adds _WIN_SUPPORTING_WM_CHECK, but NOT _NET_SUPPORTING_WM_CHECK. Indeed; I don't have a _NET_ anything. _NET_SUPPORTING_WM_CHECK is a EWHM property; x-ref http://standards.freedesktop.org/wm-spec/wm-spec-latest.html#id2577320. And ctwm doesn't do any EWMH stuff. -- Matthew Fuller (MF4839) | fulle...@over-yonder.net Systems/Network Administrator | http://www.over-yonder.net/~fullermd/ On the Internet, nobody can hear you scream.
