Hi monks!

I am running a script in Activestate Perl that uses a program running in the Cygwin enviroment. The program prints several lines of output.

my $pid = open2(*Reader, *Writer, 'primer3_core.exe' );
    print Writer "$primer3input\n";
    close Writer;
    my @result = <Reader>;
    print "@result";

Everyting seems to work fine, and the @result gets the first line of output from primer3, but then everything stops before it is printed. At least until I kill the primer3 process manually, then the script gets the rest of the output and continues. Just writing the input to a file and then doing

my $result = `cat tempfile | primer3_core.exe`;

works fine. I have no idea why it's not working with open2, especially because the author of primer3 uses open3 in one of his own perl scripts...
