what do you mean by pop-up window?

I am not entirely clear on what the problem is.  If you have a terminal 
window (i.e. an xterm or some other) and you type aips tv=local, then
2 new windows should appear.  One is the TV labeled AIPSTV-UNIX-1 and 
the other is an xterm labeled AIPS_MSGSRV_1.  There is a 2nd xterm which 
comes up in icon form labeled AIPS_TEKSRV_1.  If the MSGSRV window does 
not appear, perhaps you have an issue with xterms.  Try the command
         xterm %
A window should appear into which you may type.  If it does not, then 
you do not have the function normally provided by the program called 
xterm on which the message server and TEK server depend.  Note that many 
users do not like the message server and kill it when it comes up.  Task 
and verb messages will then appear in the terminal window in which you 
started aips.

The /etc/services fix which you did allows you to use internet TV 
instead - simply say aips without the tv=local.  For a single computer, 
either is fine and tv=local usually has fewer problems.

If you click on the close button in the XAS window, you kill XAS 
completely and abruptly.  You do not allow it to release the shared 
memory it has allocated and so eventually your machine will run out of 
memory that can be allocated.  Not a good idea.  AIPS has the command 
KLEENEX which closes the windows gracefully as aips exits.  The Esc key 
type when the cursor is in the TV window also is a graceful way to close 
it.  To get a new TV you must start a new aips.  NOte that you can run 
multiple instances of aips with or without multiple TVs.  The MSG window 
is different.  You can close it with CTRL-D in the window or the kill 
button at the top right.

You probably do not need to reinstall aips, but if you want to reinstall 
a version - say 31DEC19 - over agin.
cd $AIPS_VERSION
"/bin/rm" -rf 31DEC19
and then 31DEC19 is fully cleaned out and may be reinstalled.
