FlashMx2004 is it already worthwhile to download and install it ?
I personally don’t think so, You might wanna wait until november, when the patch is out.
I personally think so.
The only thing I’m having problems with, is the Actions Panel, which is very (did I say very already?) slow. I can live with that. 
I’d say wait. I just had to dump an entire project and go back to MX with the old approach. Some great new features… but they do me no good at all if the rest doesnt work properly.
