I've encountered a strange behaviour of mail when called in a X11 window (MIT) on a client which runs OpenWindows. The situation is as follows: The client, named A, is a Sun SLC under SunOS 4.0.3 which runs OpenWindows. On that client I've openend a xterm window from another Sun host, named B, which uses MIT X11 R4. This is done by executing the following command on A: rsh B exec xterm -display A:0 & This works almost fine execept when I call mail inside this window. If I now display one of my mail items this will cause the client to consume excessivly CPU time. I`ve found that this time is used by the OpenWindows Xnews server on A. For each display of a mail message about 30 seconds CPU time are used by that server. The mail command itself uses less than 1 second on B. The same happens when I call mail (i.e. /usr/ucb/mail) on client A within a shelltool window. And now some weierd behaviour: If I do excatly the same under a remote shell on B (from the same window), i.e. issuing the commands rlogin B, and then mail, all works fine. Also, there are no problems if I use the OpenWindow mail tool on client A. Since I've no idea what could cause this strange behaviour I would appreciate any hints.
