All of a sudden Hotmail.com appears to be displaying AMPscript. For example normally you see "View in browser" at the top of our emails and it is linked using amp script %%view_email_url%% that pulls from Exact Target. Hotmail.com on IE is now showing the link like this: %%view_email_url%%View in browser

It is showing all of them throughout the email.

Has Hotmail.com or IE recently had a change in the way they render?
