Isn’t like that. I’m sorry for late reply your message. In this case your question is technical and we need more time to check it. Also you replying again on this post and your post will show up on front page, so i think this is newer question. Sorry for this inconvenience.
Please try to disable all plugin except required plugin that come with these theme and i think this is not theme issue because several feature on these theme will not work perfectly on IE browser and will need more time to load properly.
