colouredfunk, I find any product outside of Adobe products works faster than Adobe itself; even though FD uses the Adobe rendering engine (and also links to the Flex engine, or potentially others), it doesn't have the overhead that goes with Adobe. Don't know why it is faster, though I think that FD does a lot of pre-loading, and handles re-rendering in a different way.
claudiul25, I think I have figured out your problem, though you will have to answer the last set of questions I asked. When you are "linking" a symbol (by entering a "Class" name and "Base Class" in the "Symbol Properties" popup, right?), I think you may have some confusion about what the "Class" textbox does. This is the new class name for this class, but it doesn't inherit anything. If you have *no* "Base Class" entered, it also is not even a MovieClip, no matter what you stuff inside of it! Once you add your class name to the "Base Class" textbox, and your class is extending the MovieClip class, you are now creating - via inheritance - a MovieClip, and will be able to use what's inside.
