Hi all,
I have a workbook that has been running fine for a very long time. Last week
I noticed that all of a sudden I am getting an error that states "Code
execution has been interrupted". The macro still completes the operation, but
the error box comes up.
I have not altered the code in any way for quite some time, but this error
mysteriously started happening last week seemingly out of the blue. Any clues
as to what it could be and fixes for this?

Public Sub Print_Visible_Worksheets()
Application.ScreenUpdating = False
Dim sh As Worksheet
Dim arr() As String
Dim N As Long
Const sStr As String = "Main"

For Each sh In ThisWorkbook.Worksheets
With sh
If .Visible = xlSheetVisible Then
If StrComp(.Name, sStr, vbTextCompare) Then
N = N + 1
ReDim Preserve arr(1 To N)
arr(N) = .Name
End If
End If
End With
Next sh

With ThisWorkbook
.Worksheets(arr).PrintOut
.Worksheets(1).Select <-----ERROR IS ON THIS LINE
End With
Application.ScreenUpdating = True
End Sub
