How can I prevent Comments/Notes constantly resizing and moving?

Hi,
maybe you can add to your workbook simple macro that will make all comments to fit it's content.

Sub AutosizeComments()
Dim yourComments As Comment
For Each yourComments In Application.ActiveSheet.Comments
    yourComments.Shape.TextFrame.AutoSize = True
Next
End Sub

Or if you want them all to have specific size it can be also option..
That's I guess what I would do if some comments would drive me crazy, so just an idea
Good luck.
