Just posted this to make it easier to search for info on Panes in Excel. Programming Panes can be a real PAIN!
Code:
Option Explicit
'Test & Demo Macro for Panes and Splits
'Panes & Splits operations MUST be done on the Active Window

Sub Panes_Splits()

Dim i As Integer  'misc. Loop index
'
    'Comment this On and Off to test the effects of Screen Updating
    'Application.ScreenUpdating = False    'Turn Screen Update OFF

'Show the number of Freeze or Split Planes in the Active Window
MsgBox (ActiveWindow.Panes.Count & " Panes")
'Show the index of the Active Pane
'1: Top (if 2)     or Top left (if 4)
'2: Bottom (if 2)  or top right (if 4)
'3:                   Bottom left
'4:                   Bottom right
MsgBox ("Active Pane: " & ActiveWindow.ActivePane.Index)

'Show the visible area in the active window for all of the panes
For i = 1 To ActiveWindow.Panes.Count
    MsgBox ("Pane " & i & " " & ActiveWindow.Panes(i).VisibleRange.Address)
Next i

'Turn off FreezePanes
    ActiveWindow.FreezePanes = False
'Turn off Splits
    ActiveWindow.Split = False
  'OR:
    ActiveWindow.SplitRow = 0
    ActiveWindow.SplitColumn = 0
    
'How to turn on specific panes?
'Panes/Splits are created based on the position of the SELECTION in the
'  VISIBLE area in the ACTIVE WINDOW.
'Visibility and Pane/Split IS affected by the Application.ScreenUpdating state!
'
'If the SELECTION is NOT at the top of the window, a horizontal Freeze/Split
'  will be created above the SELECTION.
'If the SELECTION is NOT at the left edge of the window, a vertical Freeze/Split
'  will be created at the left edge of the selection.
'If the SELECTION is at the Top Left corner of the visible window, the Freeze/Split
'  will be created at the center of the window, splitting the window into
'  approximately equal Quadrants.
'If the SELECTION is NOT VISIBLE in the window, the window will be reset so that
'  cell A1 is in the top left corner of the visible window, and the the Freeze/Split
'  will be created from that position.
'If Application.ScreenUpdating = False and the selection is not visible in the
'  current view of the screen, the current screen view will be split into 
'  approximate quadrants.

'Run this macro with Cell D4 prepositioned in various positions on the screen
    Range("D4").Select
    ActiveWindow.Split = True
    
    'Turn Screen Updating ON
    Application.ScreenUpdating = True

'If you need to reposition the view so that a particular cell is in the top left corner:
    'Application.Goto Range("$G$6"), True  'Force Scroll to indicated cell
