This example activates the next pane of the active window in Book1.xls. You cannot activate the next pane if the panes are frozen. The example must be run from a workbook other than Book1.xls. Before running the example, make sure that Book1.xls has either two or four panes in the active worksheet.
Workbooks("BOOK1.XLS").Activate
If not ActiveWindow.FreezePanes Then
With ActiveWindow
i = .ActivePane.Index
If i = .Panes.Count Then
.Panes(1).Activate
Else
.Panes(i+1).Activate
End If
End With
End If
