when running target.py it works fine until i close the app without
ending the process. (before 'q' is entered by the user). sometimes
python will not allow the user to click in the window and have the
ability to type after running the target window. sometimes the mouse
clicks affect a part of IDLE up and left of where the actual click was.
when i ignore this error (this is the only thing i have open in IDLE) i
must fist close out of python and reopen target.py i have used this
approach to test and find that there are no bugs in my program (at least
it works above and beyond the specifications of my class assignment),
but every once in while i will get an error when trying to use 'q' to
end the program and python will state that win.getMouse() is not a
viable term to use, because (win) is already closed yet when 'q' is used
the if statement has the close command right underneath the get mouse
command.
*note* i have coded another program specifically from John Zelle's
"Python Programming: An Introduction to Computer Science" p.160
programming exercise #1 and my get display text, get mouse, then close
window is verbatim from that in target.py and it never showed an error
in the #1's program

IDLE can't bind TCP/IP port 8833, which is necessary to communicate with
its Python execution server. Either no networking is installed on this
computer or another process (another IDLE?) is using the port. Run IDLE
with the -n command line switch to start without a subprocess and refer
to Help/IDLE Help 'Running without a subprocess' for further details.
