Autofit Script locks cells in a Protected Sheet

[lbrun01]

I am using VBA to autofit text within cells. It works great until I protect the sheet. When I enter text in an "unlocked" cell in the protected sheet, the cells autofits the data correctly however then the cells becomes "locked". I cannot go back to update the content. Does anyone have suggestions on how to fix the issue? I am using the script below:

 
Private Sub Worksheet_Change(ByVal Target As Range)
Dim NewRwHt As Single
Dim cWdth As Single, MrgeWdth As Single
Dim c As Range, cc As Range
Dim ma As Range

With Target
If .MergeCells And .WrapText Then
If ProtectStatus Then Me.Unprotect
Set c = Target.Cells(1, 1)
cWdth = c.ColumnWidth
Set ma = c.MergeArea
For Each cc In ma.Cells
MrgeWdth = MrgeWdth + cc.ColumnWidth
Next
Application.ScreenUpdating = False
On Error Resume Next
ma.MergeCells = False
c.ColumnWidth = MrgeWdth
c.EntireRow.AutoFit
NewRwHt = c.RowHeight
c.ColumnWidth = cWdth
ma.MergeCells = True
ma.RowHeight = NewRwHt
cWdth = 0: MrgeWdth = 0
On Error GoTo 0
Application.ScreenUpdating = True
End If
End With
End Sub
