Skype 5.2 switching Graphics Card to stronger one on Lion

Hi all,

I found after I upgraded to latest MAC OS X 10.7 Lion, the battery life of my Macbook Pro Late 2011 comes dramaticaly down. So I inspected that Macbook runs on AMD Graphics Card even no graphic strong app is running. After installing gfxCardStatus and closing some apps I found that Skype 5.2 does this, after quiting skype graphics card automaticaly switch to Intel one and the computer stops being warm. Alltoughts I think that Lion drains battery more then SL.
