SimpleNote insertion point moving when text is changed

Has anyone noticed or experienced the insertion point handle of a SimpleNote moving when the text string is changed?  If the text is changed back to the original string the insertion point moves back to the original location.  The XYZ alignment values don't change only the relative location of the insertion point handle.  My understanding is the insertion point handle and the XYZ alignment values should coincide.  I've tried  different justification options with similar results.  I believe this is a bug since there is no reason I can think of for the insertion point to move since it is effectively the origin for the note.
