IE 8 Height Issue

I have not been able to figure out what the height issue I am having with IE. On all but one dialog, the dialog comes in the correct size. but note the issue on ie8-myfintasks.jpg which is short, but the ie8-mytasks.jpg is correct. The table contents is dynamic from an ajax call and the table structures are identical and there's no html or other markup in the data.

I init the dialog in the document ready function...

$("#itsDialog").dialog({

autoOpen:false,height: 350,

width: 500,

modal: true,

buttons: {"Close": function(){$(this).dialog("close");}}

});
