I have been working on a web app that uses IFrames for our edit
screens. A main window contains static information, while an IFrame
contains the editable page. I use javascript from the outer page to
cause the inner page to post back, but when I turn on smart
navigation, it locks up IE. I tracked it down to the actual
[form].submit() call in javascript, then its locked up. I set a couple
of hidden form elements that I use for tracking, then submit its form.
Here is the code here:

// submit the form to process here...
document.frames("ifWizard").document.forms[0].saveresult.value = "";
document.frames("ifWizard").document.forms[0].savemode.value = "1";
document.frames("ifWizard").document.forms[0].submit();

Ive been researching how smart navigation works, but it seems like it
shouldnt have a problem with this. I thought it was my code at first,
but all indications are leading to some sort of bug in smart
navigation. Has anyone else came across this problem?
