Lately I've come across an annoying bug. Whenever you try to add a cast or crew member, the most popular movies attached to a suggested profile appears (which is great). However, the problem is when those three suggestions are "too long"/have too many characters. See screenshot: http://img36.imageshack.us/img36/9997/7sc6.jpg

Then the suggested titles jump down and block the Create it... option or the option below if there are more profiles with the same name. I think this bug may have caused some duplicates at times. In this example it's still pretty obvious that you click on the image, but there have been others where it wasn't quite as simple.
