webbrowser Pop my program to the topmost

Hi
if i use some pages that are supposed to open in a new window and my program is minimized then it pops to the topmost

Code:

---

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick

 webbrowser1.Navigate("http://www.vbforums.com/misc.php?do=whoposted&t=311501")
end sub

---

How can i solve that?
