I've run into a problem that seems to have erratic results when I format
my resume using LaTeX.  I'm using TeX 2.93, sometimes I get weird spacing
in the middle of words.  The spaces aren't consistent throughout the
document (ie. the same word appears later, and is spaced normally).  For
example the word "Software" had a little extra space between like
so "Soft_ware" (NOTE: that the "_" isn't a full space, it's like a millimeter
off...)  It's annoying.  I've had the same problem with the "\tt" teletype
font when I say "lenny@icus.ICUS.COM" it would put a space between the I and
the C in "ICUS".   I have small amounts of extra space between the word
"Accounts" after the "n" and before the "t". 

What can I do about this?  The dvi file is processed and converted to
Laserjet+ output with dvijep to be printed on a Brother HL-8e laser printer.
Since I'm new to the TeX-world, it could be a procedural problem ... where 
should I look?
