DD Mega Menu getting cut off

[alaska]

1) Script Title: DD Mega Menu

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...ddmegamenu.htm

3) Describe problem:
I just setup DD Mega Menu, but the drop down menus are getting cut off after about a row. Probably about 50 pixels. I can manually site the height of the mega menu div, but shouldn't it size to fit the contents? Thanks!

Updating the DOCTYPE on the page to the same one used in the demo seems to have resolved this.
