Can't Edit Notes

Hello All,

After adding a Note or SimpleNote to my drawing I can save and edit without any problems.  Now here is what puzzles me.  I then close and re-open the file and try to edit the note.  Now if the note is only "one line" I can only edit through the Properties window or click on it and delete or move it but if the note has "two or more lines" I can't edit.  The command window says this "Anonymous block cannot be edited".  The only thing I can do is move or delete it.  Please help and thank you in advance for your help.
