Parts of pages not displaying in IE

Pages in our collection are not displaying correctly in IE. For example in Firefox or Chrome has text and thumbnails at the bottom, while in IE only the title shows. Or there should be images and text but IE only shows one image.
Any suggestions about what might be causing this?

It looks like your text got copy-and-pasted from Word?

Looking at the source, it contains a huge amount of HTML comments (a specific type which only IE parses, actually).

Re-pasting in your text might fix this problem (an easy way to get at the text without the comments would be to copy from the page as displayed in Firefox).

Thanks! Our text was pasted from Word. I've delete the comments and everything is working now.
