<p>Just as an extra to the original question, there is another way round it all. We have consistently run two computers\laptops through a 2 in, 1 out manual vga switch. This means that on the odd occasions when we are still playing around with, say, a PPT presentation, we can do it on the other computer while openlp is up and being used. Just swap out to the other computer when the PPT is needed. Equally, it's possible to easily run 2 instances of openlp (or Powerpoint) which can sometimes be useful on larger events and conferences, since one instance can be used for those improptu moments.</p>
