Moving Form While App Is Running

I'm developing a VB.net windows form app in Visual Studio 2010. I want to be able to drag the form to another location or minimize it while the app is running. Is that possible? Here's and example. I have a form with 1 button. Here's the code associated with the button:

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim time0 As Integer
Dim time1 As Integer
For time0 = 0 To 1000000000
time1 = time0
Next
End Sub

I can move the form or minimize it until I push the button. Then it freezes until the code stops running.
