Captivate is not a Presentation tool but an eLearning tool.
Do you truly need to show the application running in real time or just the appearance of? Captivate has an awesome screen capture/software demo feature. You may be able to very nicely 'fake' what you are trying to show?
Thanks for the reply. Yes, it needs to be in real time.
I think I've found a solution ...
AnalogX AutoTab switches between active applications every couple of seconds. Perfect for tradeshow displays or other times when you would like your computer to switch through a variety of programs in an automated fashion.
