ATA 3.6.4 | WP 3.1.1. - Dropdown Menu 1- IE error behavior

Since updating to WP 3.1.1.

Menu 1 behaving oddly - in Internet Explorer.

BTW, bugfixes applied for ATA 3.6.4.

Menu 1 Dropdown Menu has Animate Page Menu Bar [with Javascript] set to Yes

This had worked wonderfully, however, following WP 3.1.1. in Internet Explorer 8 (and IE 7)

the dropdown menu appears totally Blank

then you have to mouse hover down for the Menu Items to slowly appear, one by one.

there is a white space appearing at the bottom of Dropdown menu.

also, oddly, the Dropdown Menu now displays extended in length!! (over the image, whereas should end on image border).
