iFrame crashes browser window when launched from LMS

All,

I'm hoping maybe someone has seen this happen. This works perfectly when launched directly, however, when the course is launched from the LMS, the entire window crashes.

I have an iFrame that has a couple components:

1.) javascript at the "launch page" root -- this refreshes the iFrame, ensuring the content is current:

function reloadIframe() {

frm=document.getElementsByName("iframe")[0];

frm.src=frm.src;

}

2.) a button in the "launch page" that

executes the javascript in 1,

and then kicks off a Run Action Group which contains code that calls the iframe via custom HTML: [IFRAME SRC="a001_task_lists_topic_one.html" NAME="iframe" WIDTH=400 HEIGHT=350 frameborder=0] [/iframe]

If anyone has had the same experience and has solved it, i'd appreciate your feedback.

Thanks!

Lisa
