CellPointer (rectangle around selected cell) not visible

[Henk]

To make some data input sheets more user friendly, I created the possibility
for the user to choose whether he may select locked cells or not. To disable
the access of locked cells I wrote the following code :

Public Sub InputModeLock()

Application.ScreenUpdating = False

Dim BackSheet As String
Dim BackCell As String
Dim BackCellFound As Boolean
Dim StartCell As String

BackSheet = ActiveSheet.Name
BackCellFound = False
StartCell = ActiveCell.Address

If ActiveCell.Locked = True Then ' Just to direct the CellPointer to an
unlocked cell

Do While ActiveCell.Row > 11
ActiveCell.Offset(-1, 0).Range("A1").Select
If ActiveCell.Locked = False Then
BackCell = ActiveCell.Address
BackCellFound = True
Exit Do
End If
Loop

If BackCellFound = False Then
Range(StartCell).Select
Do While ActiveCell.Row < 100
ActiveCell.Offset(1, 0).Range("A1").Select
If ActiveCell.Locked = False Then
BackCell = ActiveCell.Address
BackCellFound = True
Exit Do
End If
Loop
End If

Else

BackCellFound = True
BackCell = ActiveCell.Address

End If

ActiveSheet.Unprotect Password:="xxxx"
Range("A2502").Value = True
ActiveSheet.Shapes("InputLocked").Select
Selection.Delete
Sheets("Globals").Select
ActiveSheet.Unprotect Password:="xxxx"
Range("InputModeUnlocked").Select
Selection.Copy
Sheets(BackSheet).Select
ActiveSheet.Paste
If BackCellFound = True Then
Range(BackCell).Select
End If
ActiveSheet.EnableSelection = xlUnlockedCells
ActiveSheet.Protect Password:="xxxx"

End Sub

This works okay, but preparing the file for the user I run some code to
protect, hide, reformat ecetera etcetera. To put all sheets where appliccable
in locked position, I call the InputModeLock routine. Which again works
perfectly. The only thing is that my CellPointer (the rectangle around a
selected cell) is gone. In the upper left corner of my screen, where the
selected cell address or name is displayed, I can see that I can select the
unlocked cells, but I do not see the CellPointer. The moment I input anything
in an unlocked cell, which is possible, then the CellPointer is back
immediately.

The code calling InputModeLock routine is :

Sheets("Sheet x").Select
Rows("500:5000").Select
Selection.EntireRow.Hidden = True
ActiveWindow.DisplayHeadings = False
ActiveWindow.DisplayGridlines = False
If Range("A2502").Value = False Then
Call InputModeLock
End If

Anyone any clue?

Thanks in advance,
