memory leak in IE 6.0

We have WindowsXP pro. Service Pack 2, Internet Explorer 6.0

We have published/saved a simple ppt (Power Point) file having 24 slides as mht.

On playing this mht file in Internet Explorer 6 continues for several hours, we can observe a memory leak of about 5MB per hour for IE. After 15 minutes of play we also observe blank white screens in between two slides. And after 10-12 hours of Playback the IE is crashed.

How can we resolve this misbehavior of IE on playing mht file which has been published using PowerPoint

Thanks in advance. Any kind of help is highly appreciable.
