Is Vista and Flash CS3 performance issue solved?

My performances in Flash CS3 are very poor. When I try to scroll up-down/left-right I got slideshow. When move the timecursor to view the timeline I also get slideshow. Same when moving objects or scrolling the library. Searched google, do the compatibility settings and the only batter thing I get is smoother scrolling of the code. Nothing more. Is this solved?

Im running C2Duo with 4gb 800 ram with Vista x64 SP1

(Same with Flash 8 Pro)
