[xubuntu-users] I still have the black rectangle on my desktop.

I ran *ps -A | grep $(xprop _NET_WM_PID | cut -d' ' -f3)*

and this is what I get:

2264 ?        00:00:00 xfce4-panel

2264 is output in red.

I'm still so new to Linux, I have no idea either why running those commands
gets that information, nor what the information means, except in the
vaguest sense.  While I'd love to remove the black rectangle, I'd love even
more to understand how it happened and how the command to get that
information works and now how to use the info to get rid of it.

I'm still one of the Rikki-Tikki-Tavi sort...
