iFrame support in IE9
IE9 has changed how IE handles iframes and that is the cause of this issue.
The portlet will run fine if you are running in a compatibility mode. I have
included the link to the IBM Support statement below. I believe there is also
a Portal support statement about how to modify certain .jsp and jspf files to
take care of this, but I have not been able to locate it. I will try and find
it and post that too. Let me know if that helps your situation or if you have
other questions.
