in reply to developing in vim and tmux

So I've been using this. One problem I noticed is if I have 2 panes split side by side sitting on top of the pane created by vimux and run the perl code, the output does not get sent to the vimux pane but to the other pane. Do you know how to force the output to the pane generated by vimux?

$PM = "Perl Monk's";
$MCF = "Most Clueless Friar Abbot Bishop Pontiff Deacon Curate";
$nysus = $PM . ' ' . $MCF;
