Logic X Mixer Window sluggish

I open my old Logic 9 session and the mixer window opens very fast and scrolls back and forth very fast.

On Logic x the mixer window opens the first time blank and then a second later the faders appear. then scrolling back and forth is very slow. once the mixer is opened once then it opens with the fader graphics but opening the mixer window is very slow. A Lot of graphic things in Logic X are way slower then Logic 9.

Does anyone have a fix for this. I have logic on my SSD drive and I have 20 gigs of ram and a NVIDEA GTX-284 1g Graphics card

thanks
