Lock/unlock form button

I've successfully created a button that locks/unlocks all the fields in a
form. In addition, it keeps all fields unlocked during initial record
creation, but requires the user to use the button whenever any fields in the
form are edited. This was accomplished by following the instructions and code
(see pasted at bottom of this post) at the following web address under
"Double-Action Command Button" posted on 3/28/08:

http://www.msaccesstips.com/labels/m...%20forms.shtml

This does almost exactly what I want, but I'd like to have one of the fields
on the form (a combo box field that looks up and returns a given record in
the rest of the form) not lock each time. That is, I'd like it to remain
unlocked and available for repeat use without having to click the lock/unlock
button each time. Is this possible?

Thanks


The code portion of the application is as follows:

Private Sub Form_Current()
If Me.NewRecord Then
With Me
.cmdEdit.Caption = "Edit"
.cmdEdit.ForeColor = 0
.cmdEdit.FontBold = False
.AllowEdits = True
.cmdEdit.Enabled = False
End With
Else
With Me
.AllowEdits = False
.cmdEdit.Caption = "Edit"
.cmdEdit.ForeColor = 0
.cmdEdit.FontBold = False
.cmdEdit.Enabled = True
End With
End If

End Sub


AND


Private Sub cmdEdit_Click()
Dim cap As String
cap = Me.cmdEdit.Caption
Select Case cap
Case "Edit"
With Me
.AllowEdits = True
.cmdEdit.Caption = "Lock"
.cmdEdit.ForeColor = 128
.cmdEdit.FontBold = True
.Refresh
End With
Case "Lock"
With Me
.AllowEdits = False
.cmdEdit.Caption = "Edit"
.cmdEdit.ForeColor = 0
.cmdEdit.FontBold = False
.Refresh
End With
End Select
End Sub
