I was just trying to get started with Flashdevelop and Flex 2 SDK as the compiler and I’m running this kind of basic test code.

It compiles fine and traces what it should but when I close the .swf tab, the whole program crashes. Anyone got any ideas why that is happening?

My project just has 1 file, cool.as
