AirRabbit <grin> excellently put.
Thridle Op Des. Interesting comment about Flash (I have one foot in I.T.). It's a system of choice for delivering web based CBT as its about as non platform specific as you can get, if someone has a web browser they can get the Flash plug in (if they haven't already). Consequently I'm surprised you can't use a Mac. As far as being memory hungry - well, for CBT, thats a lot to do with the resources and how they are managed. Flash in itelf is a small system overhead.
Thanks for the comments everyone.
