I was able to recreate this in the demo version.  In word, type in the text : The quick brown fox jumped over the lazy dog.  Do a copy, then in CE do a paste from word.  What is inserted is  The quickbrown foxjumped over the lazy dog.  Notice the space has been remved between 'quick' and 'brown' and also between 'fox' and 'jumped'.
