iesample browser: memory issue

Hi All,
I'm using a mobile hand held OSdesign in CE 6.0. I included iesample browser
in my OSDesign. I'm able to browse websites. However when i try to browse
sites which require more memory than what is available at that point, the
iesample is giving data aborts. Is there an option to restrict memory usage
of IE.

Also how to set IE to open mobile pages like MSN homepage rather than normal
web pages.

Thanks in advance
