Sounds as if your cells may have invisible characters or malformed
box structures that affect the notebook's evaluation.  Can you try
the following for me?

1) Open a notebook which has a cell behaving as you describe.

2) Select the bracket of one of the cells that misbehaves.

3) Perform the following front end menu command:

Edit -> Copy As -> Cell Expression

4) Post the content you just copied to the clipboard.
