Crunchy text in .swf export + sluggish behavior

Help! There have been 2 main problems in my new experience with 2004 Professional;
1–I open an MX file of my website and when I export it in 04Prof., (both as a Flash Player 6 + 7 document) the text + some vector images come out very blurry + crunchy, practically illegible in some instances;

2–the other problem is that when I go back and forth from the root timeline into a symbol or group, the program constantly, CONSTANTLY has to think/ displays the rainbow wheel - 1 or 2 times I can see, but this happens ALL the time, and workflow suffers severely; MX never had this problem.
Can anyone help me with this/ has anyone heard of this?

Any help is most greatly appreciated.
