A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
The comments have moved, possibly as a result of hiding rows or columns or deleting cells.
I have experienced the same from time to time.
I would run a macro to re-position all the comments; something like this:
Sub RePositionComments()
Dim WS As Worksheet
Dim C As Comment
Dim iSave As Integer
Const MaxWidth = 200
iSave = Application.DisplayCommentIndicator
Application.DisplayCommentIndicator = xlCommentAndIndicator
For Each WS In ActiveWorkbook.Worksheets
For Each C In WS.Comments
C.Shape.Left = C.Parent.Offset(0, 1).Left + 10
C.Shape.Top = C.Parent.Offset(0, 1).Top - 10
Next
Next
Application.DisplayCommentIndicator = iSave
End Sub
