Hi t-min. Welcome to the forums.
Hm, that layout is a bit contorted and needs some tidying up . For some reason the whole top section is contained in a form that's leaving a lot of empty space in IE, as are these styles too:
<font color='"#FF0000"'>height: 90px;</font>
<font color='"#FF0000"'>height: 65px;</font>
This layout could be much neater and simpler, though, as it's not complex.
