Two problems with Norton 2010

Hello to all,

I have two problems, first one is whenever i load recent history, it takes few more seconds to open as compared to NIS 2009, and i think i have a good system speed, so it should not happen each time i open it and take a good amount of CPU.

Second problem is whenever i rate my Windows Experience Index, it hangs, it happens only when NIS 2010 is turned on. I have set all settings to aggressive and on high. But i am not able to figure out why Norton make it (Windows Experience Index process) freeze. Strange thing is when i turnoff Auto protect and sonar, all things work fine..
