Overlapping letters in Terminal

[Todd And Margo Chester]

Hi All,

Just installed Xfce 4.8 from EPEL on my new SL6 server.

Problem: "Terminal's" letters will overlap every so often.
It is like two letters occupy the same space, then a long
blank space to the right.  This both when I am typing and
when results are displayed.

Any idea what is going on?

Xterm, after downloading the extra fonts for X11, does not
have the same problem.  (Wish I could get copy and paste
in Xterm.)  Xterm works fine.

Many thanks,
-T
