using LWP getting a PDF file which comes up blank

I'm trying to link a web application to a clinical portal in a hospital. =
The portal links various web enabled applications so the clinician can see =
things from all sorts of databases all in one view. I am trying to =
display from our Electrocardiography application a PDF file of an ECG =
using LWP for display within this portal. When I get the return of the =
PDF, the adobe acrobat plugin pops up but it comes up blank. For multi =
page ECG's it comes up with multiple blank pages. I have saved this =
blank file and looked at it, it seems like it has the same size as a PDF =
which displays in the inherent web application. Loading this saved file =
into Adobe from the desktop, its still blank. Some characters hex code are =
different though (so I'm not sure this is an encoding issue).

Anyone have any thoughts why the PDF file displays

The code I'm using is:

#!c:\Perl\bin\perl.exe

#################################################
## GEMuse_detail.cgi =
#
## ==================== =====
==================== #
## - displays patients individual EKG result =

use CGI;
use CGI qw/:standard/;
use LWP::UserAgent;

Didn't read your code, but: Are you processing the PDF file at any stage
as a text file? If so, stop doing that :)
