Description From 2008-02-23 07:21:56 PST
On delta.com in the award calendar path (https://www.delta.com/awards/home.do?EventId=ENTER_APPLICATION, submit cities to search on, calendar appears), the calendar display is extended. The header space above the calendar display is much longer than it should be.

This is actually the 2nd time I've hit this ASSERT in the last ~36 hours - the first time was on a site that can't be posted and my initial attempts at a quick reduction failed.

After talking to Mitz, this crash is unrelated to the rendering issue.
