I've noticed that although my old project compiles with ASC 2.0, sometimes the runtime behavior is different/wrong. For instance sometimes I see that library symbols will not behave the same, perhaps when using goto framelabels. I can't yet exactly say under what circumstances its breaking but it definitely has to do with attached movieclips at runtime. Sometimes the graphic does not land on the frame I expect it to.
Are there compatibility flags that the mxmlc compiler can take to make it behave more like the Flex compiler of the 3.5 era? I dont have any actual Flex dependencies, its all Swfs and actionscript. But the project works perfectly using that compiler. Unfortunate because I want to take it mobile, and I wanted it to all work using Adobe's new compiler.
thanks a bunch.
