This optional window is used to display all kind of messages including
the ones written to stderr by external commands. The main advantage
of using it is
that its contents are saved in a scrolling list until the
program exits. Disabling this feature by setting the resource
useLogWindow to false will generate popup windows to display
messages. The stderr of external commands will appear on Pcb
s
stderr which normally is the parent shell. I suggest you iconify
the log window after startup for example by setting *log.iconic to
true in the resource file. If raiseLogWindow is set true,
the window will deiconify and raise itself whenever new messages are to be
displayed.
