I also had the problems with the programm crashing while deleting clips. Saving the project helped a few times. I find it more annoying, that you can only work in 4:3 format, and only VGA, and not at all in 16:9 Format. Why? This limitates the possibilities of using the animation in a "broadcasting world" without black borders or stratching the whole animation. Please change that! Because the drawing tools are quite cool and it is fun working with them and the onion skin.
