MX 2004 is a RAM hog and is the only graphics program that can't seem to work with a stylus pen. HUH??? Macromedia is also just plain incapable of getting the WACOM pad and the application to work.
MX 2004 just churns on memory too, and does not seem to provide anything new to make it worth it. It hangs on text selection, it takes about 30% longer to do stuff now. I hate to say this, but its TERRIBLE. Don't bother until the patch is available...
