This is due to the wysiwyg text editor. I tried with tinymce, ckeditor, niceeitor. But my Entity Reference View Widget is not loading if any one of editor is added to any fields in content type. But without editor (Plain text editor for fields) Entity Reference View Widget popup is working.

I just tried to add ckeditor and jquery 1.7 and it was working for me... Did you check if there's any js error in the console? I need more information in order to help you.
