Cursor in textbox keeps moving to begining during key-in

The problem is caused by the (".00") If you remove it the problem goes away.

Passel has given you a very nice solution. The textbox your entering data into will not be adding the .00 format as your typing so I would add that function to the Validating Event

    Private Sub tbHeight_Validating(sender As Object, e As CancelEventArgs) Handles tbHeight.Validating
        Dim decNum As Decimal
        If Decimal.TryParse(tbHeight.Text, decNum) Then
            tbHeight.Text = String.Format("{0:n2}", decNum)
        End If
    End Sub
