Jumpy seat map scrolling in IE9

I just got the IE9 download, and noticed that the seat selection screen on PEO is jumpy when you are trying to scroll through an area. (not as jumpy as Amy here...) It seems that it is limited to IE9 and also limited to this one screen, and also limited to seating areas that have more than, say, 400 seats.

The reason for the jumpyness - the seats are actually little gif images, which are put through an image filter, which will rotate them to the top, left, right, bottom depending on where you say the stage is. When IE9 does this for 1000 little .gifs, it tends to freeze up a bit. firefox, IE8, and Chrome had no problems. The javascript has the following lines;

var img_filter = 'progid:DXImageTransform.Microsoft.BasicImage(rotation=2)';
...


Taking the filter property out of the image tag in seats_plan.asp line 226 fixed it right up, and actually had the page loading faster in all browsers. You may have to rotate all of the little seat images with an image editor so that they point toward the "stage".
