Access 2007 - VB code

My OS is win 7 Prof 64 bit and I use office 2007.  In my Access 2007, I have the following code :

Private Sub cmdCopy_Click()
' This procedure runs when the Copy button is clicked.
On Error GoTo Err_cmdCopy_Click

    ' Set focus on the results.
    Me.txtResults.SetFocus
    
    ' Copy the results to the clipboard.
    DoCmd.RunCommand acCmdCopy

Exit_cmdCopy_Click:
    On Error Resume Next
    Exit Sub
    
Err_cmdCopy_Click:
    MsgBox Err.Number & " " & Err.Description, vbCritical, "cmdCopy_Click"
    Resume Exit_cmdCopy_Click
End Sub

Select allOpen in new window

but when the button is clicked, it does not seem to  highlight all the text, it flickers before the start of the first character as the highlighting is from right to left, and sometimes I wonder if all the text have been selected.  
Is there any sure thing to do in code, that will highlight all the text, without any reasonable doubt?.
