If it works on your pc, but not on someone else's, my first guess is that they
didn't allow macros to run--either a security setting is too high or they
answered no to the "allow macros" prompt.

I have added the following VB code which works on my spreadsheet, but when
ther users access it the row height remains set - can anyone help?

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
Dim ProtectStatus As Boolean

With Target
If .MergeCells And .WrapText Then
ProtectStatus = Me.ProtectContents
If ProtectStatus Then Me.Unprotect ' "password"
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

If ProtectStatus Then Me.Protect ' "password"
End If
