RadioButton Checking Issue

Question

I have 7 radio buttons on my form and when I click to check one of the first three, it takes two clicks to do so, and the others flash for a split second. Is this a glitch? The other 4 won't even let me check them. Clicking a bunch of times just results
in an unchecked radio button.
They aren't in any group boxes, and there aren't any timers on the form.
How can I fix this?

Hi Bgeo99,
As image there 3 types of controls label1, groupbox1, 7 radiobuttons in gpbox
Public Class Form3
    Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        For Each rb As RadioButton In Me.GroupBox1.Controls.OfType(Of RadioButton)()
            AddHandler rb.CheckedChanged, AddressOf RadioButton_CheckedChanged
        Next
        Me.RadioButton1.Checked = True
    End Sub
    Private Sub RadioButton_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)
        Dim rb As RadioButton = CType(sender, RadioButton)
        Me.Label1.Text = "BackColor is : " & rb.Text
        Me.Label1.BackColor = ColorTranslator.FromHtml(rb.Text)
    End Sub
End Class
thanks.
