Camtasia - Experience with

I spent the whole weekend creating work in Camtasia. I used it at school this morning. Let me discuss the problems. When Camtasia opens it defaults to a 1024 * 768 screen. For Camtasia I used the 'whole window'. When I viewed the work on the data projector with my class we could not see the work as it was too small. In future I must make sure that I make a video with 800 * 600 settings as it is so much clearer.
