How do I overcome IE8 getting "stuck" in SCORM 4th Edition Compliance Test SX-05?

I am posting this in the off chance the开发者_JAVA技巧re is a SCORM expert out there that may have seen something similar.

Internet Explorer 8 gets "stuck" on step 14 of test case SX-05. Something doesn't trigger the continue. No amount of debugging and tracing reveals anything. It's as if the test case is "overwhelming" IE8's slow JavaScript engine. All other tests run fine in IE8. This one is quite complex, but there are others of similar complexity.

Install Chrome. No one can fix IE

Have you tried pausing the test before you get to SX-05, closing the browser and then resuming the test? That might help.

Are you sure it is an IE issue? We have successfully run the 4th Ed test suite many times without issue. If the test always stops at the exact same place, it seems unlikely that it is a resource issue. At what point does the execution stop?

This turned out to be rather obscure. Our LMS was writing a loading page to the content iframe before loading the actual SCO.

window.frames.contentFrame.document.open();
window.frames.contentFrame.document.write(html);
window.frames.contentFrame.document.close();

I changed the loading page to a static HTML page and everything chugged along fine. Modifying the document that way screws up some window events on Firefox and IE.
