I have a problem with differing results between IE and Firefox.

On the following page http://gpsactivitymanager.com/events...8-d5f1b0de451c

If you select the "splits" option (top Left) then you get a table display bottom left. In Firefox the table displays correctly and has a scrollbar if it extends outside its height, in IE however the table just extends off the bottom of the page.

The table is contained within a DIV with the following style
Code:
.scroller {
    height: 30em;
    overflow: scroll;
}
Any ideas on how I can get the scroll bar to work in IE ?

Thanks in advance
