There was another problem that just appeared today where IE was popping an error saying “Internet Explorer cannot open the Internet site…Operation aborted”. Web search indicated people saw a similar problem when using the Google Maps API, evidently because IE doesn’t like scripted changes to a table DOM before the rendering finishes:

The suggested change was to wrap the JS inside a setTimeout with wait of 1ms. That worked for me.
