I am using Gnome and Sawfish right now, but observed
very similar behavior with OroborOSX 0.8p3, so I
believe this is an XDarwin issue.
What happens is this. I launch an xterm, and from that
xterm I type 'mm', which launches the MeetingMaker
application. MeetingMaker immediately creates a
docked icon called 'mmxp' that does not seem to
correspond to any real window. This weird icon gets
randomly mapped to other windows, such as xterms,
and the whole layering thing gets confused, causing
windows to look focused but not accept keystrokes.
This happens every time with Meeting Maker, very
reproducible. There is no window in existence with the
name 'mmxp', but the window manager seems to get
confused and map it to other windows. Then, they get all
flustered, and for example, bringing a window to front
makes it not really come to front any more but just hang
back, while another window will get the keyboard focus
even though I didn't click on it.
