When I first open Hotmail the CPU usage shoots up to 100% for a while and freezes the laptop.

It then drops and I can send/compose emails but it rises again to 100% and freezes again. Sometimes I cannot get out of it using alt/ctl/del and have to force close the laptop.

I believe this problem is caused by ad cookies on Hotmail.  When the freeze occurs,  'waiting for '   mookie1.com is constantly cycling at the bottom of the screen.

How do I get around this?
