I log on to hotmail/outlook as normal but after a couple of seconds the screen turns white - even if I refresh the page.  I use a Macbook Pro with Safari, same as the user that posted with exactly the same issue. Is there a link to our problems?

I have changed nothing and my local apple retailer wants $70 to even look at my computer! I log on with my work computer (fairly new using windows) and the hotmail works fine. Why the sudden change yesterday?
