<p>I would like to know if I can open 2 different diagrams using MS Visio and each diagram have its own window. I've tried in several ways, but I always end up with 1 Visio window ...</p>

<p>I'm using a triple monitor setup and I'd like to put one diagram to each side of my main monitor.</p>

<p>PS: I'm using Visio 2007 here.</p>
