Maybe just me but I found fork a little flakey under Windows.
It's not portable but you could use this inside an OS specific flag to create a separate process:
use Win32::Process;
my $ProcessObj;
Win32::Process::Create($ProcessObj,
"c:\\Perl\\bin\\perl.exe ",
" $temp_file ", ### Script to execute
1, ### If set to 0 this prevents children
### writing to STDOUT which is BAD...
NORMAL_PRIORITY_CLASS,
".")
|| die ErrorReport();
Look up the docs on win32::process and do a search on this site (the dos are a little hard to read, IMHO, so be prepared to experiment). You should be able to get the two process communicating through temporary files if you can't get them to cohabit happily on STDIN.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
