Thanks, Nasser M. Abbasi, for kindly making the test of \int\limits 
_{-\infty}^{+\infty} on your computer and for providing some information 
about the software on your computer, including how you run pdflatex and 
LaTeX2HTML.  I get the impression that the latex and pdflatex commands may 
run very simlar programs, if not exactly the same program because something 
about PDFLaTeX or some similar spelling appeared when I executed a command 
of the form "latex File.tex" on my computer.  I tried matching a few things 
on my computer that you did not your computer, for example using HTML 
version 4.0 instead of 3.2, using $DVIPSOPT='-E'; in 
/usr/lib/latex2html/l2hconf.pm, etc.  But unfortunately on my computer I 
could not get rid of the unwanted black line segment under the integral sign 
and its limits of integration.

It appears that you and I have recently been using the same version of the 
TeX Live "Base," namely including version 3.1415926 of 2009 of TeX Live. 
However, you have been using ../TeX/Base in a Debian system called Ubuntu, 
whereas I have been using it in an RPM- (RedHat Package Manager-) based 
system called OpenSUSE 11.3.  For the moment I am going to assume that the 
Debian-RPM difference by itself is unimportant with regard to the unwanted 
black line segments.  It is nice that you have a working situation for 
\int\limits _{-\infty} ^{+\infty}.  So, if you don't mind, I would like to 
sort of probe it in order to see where my trouble might be.  Of interest to 
me are your versions of LaTeX2HTML, which is part of /TeX/Utilities and 
Netpbm, which I think may include the program pnmcrop, which I think is very 
important in cropping images.  So please report your installed versions of 
those software packages to me.  I saw that on your computer the command 
"latex2html -v" unfortunately I think did not result in a display of the 
version of LaTeX2HTML you are using.  So if you don't already know them, 
please note your versions of latex2html and dvips or dvips(k) by looking at 
the latex2html output after inputting a latex2html... command.   Also please 
type "netpbm -version" and "perl -v" and report your respective installed 
versions of Netpbm and Perl to me.  Thanks.
