I have a document originally written in Word 2003, but I have converted it to PDF and RTF and even opened it in Word 2010.

In all cases, I see a line of small square dots that appears always (I think) between two paragraphs. I cannot select that "line" with the dots in it, in order to delete it.

If I select part of the previous paragraph and part of the following paragraph, then press Delete, those bits of those paragraphs disappear, but the line of dots jumps to the paragraph break between the next two paragraphs.

Most interesting - to me - is the fact that, when I use a Hex editor to look at that bit of the file, it shows nothing between the 0D 0A of the paragraph break.

I have tried everything I can think of to get rid of this.

Can anyone help me?
