Flash Professional SOOO SLUGGISH

Someone please help me out!;
I’m running Flash MX Pro on a Mac Dual 800 G4 and it is the most sluggish program I’ve ever used - The only other Aps I have open is my Mac mail and friggin iTunes - Photoshop ran faster with TWICE the Aps open, messing with files in the high Megabytes, as I’m dealing with files well under 1 megabyte in stupid Flash; This superSlowdown occurs on EVERYTHING within the program, including;

–jumping from one Flash document to another;
–entering and exiting symbols;
–exporting an .swf

I downloaded this Ap from Macromedia and the only Prefs. I’ve changed are my actionscript string + statement colors - thats all. My workflow is gravely slowed down and it is beyond frustrating.

Has anyone heard of/ dealt with this? Anyone have any suggestions?
Anything is appreciated.
Cheers,
