Yea i had to keep clearing cache on MBP every once in a while. got fed up so i just decided to install Firefox for hotmail use. Then gave up and moved everything to Gmail IMAP.
It was a complicated and horrid procedure.
I used a friends Desktop running outlook.
I downloaded and installed Outlook Connector and let Outlook download and synchronize all of my folders and sub folders to the computer.
Then i added Gmail IMAP to Outlook and dragged everything over into GMail account.
Deleted everything off Outlook.
Just thought i would outline a procedure for anybody moving off Hotmail, and need to keep stuff.
