IE javascript debugging suggestions?

[David Gibbs <david@xxxxxxxxxxxx>]

As much as I really dislike IE, I realize a lot of people use it ... so
the fancy shmancy stuff I've been adding to the archives has to tested
in both Firefox and IE.

Problem is, I'm having a devil of a time figuring out what is causing IE
problems with some of the stuff I'm doing.

I've got a page that renders _fine_ in Firefox ... but when I try to
display the same page in IE, it displays half the page, then pops up a
dialog indicating that the page could not be displayed and the operation
was aborted.  When I click the OK button, it takes me to a built-in page
that tells me there was a connection problem.

Because I get the error just after the content that is manipulated with
javascript is displayed, I know the problem is occurring there ... but I
can't figure out what is causing IE problems.

I've encountered this on both IE 7 and IE 6.

Does anyone have recommendations for diagnosing javascript problems with
IE?  I've tried MS's javascript debugger, but can't figure it out.

Thanks!
