wordpress.com stats not working right

Hi,

I have been checking the wordpress.com stats and I am pretty sure that it counts me as a visitor. I think I know why: every time I click the “View site” button, it logs me OFF!! How do I keep myself logged ON???

Also, I think my statistics keeps mixing together: the ones from my old host (wordpress.com) are mixing with the ones from my new host (on ww.wp.xz.cn). What to do??

Thank you!
