"Folding" of text containing Math regions

I have voiced this before but thought I would again for Prime 3. I use insert Math region alot. However if I save a file with text and math regions within the text, when I reopen the file much of the time the text folds at the math region, that is everything from the Math region on is put on the next line. This usually interferes subsequent formatting. I then have to reformat the enire file, particularly if this happens multiple times in a file.
