Google Chrome and hotmail

I have been testing Chrome for the few days and I must say that the performance is much better then Firefox. I have tested it with the websites I use most often and until now I have got problems with only one site - the mcp member site. Also when I connect to hotmail, I get the browser upgrade page( I have added a screen shot below). I remember this page because in the very beginning I used to get it with Firefox too and now Firefox has made it into the list of browsers to upgrade to.
