fire mouse_enter event with mouse already down

[kebo]

hey all...
I need to fire an event when the mouse enters a panel with the mouse button already down. It seems the standard mouse enter, mouse move, etc events don't fire when the mouse is already down. With test code i'm using, all of the events fire when the mouse button is up, none fire when the mouse button is down.
any ideas?

edit...
here is my test code..

Public Class Form1
 
 
    Private Sub Panel1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Panel1.MouseDown
        Debug.Print("MouseDown")
 
    End Sub
 
    Private Sub Panel1_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs) Handles Panel1.MouseEnter
        Debug.Print("MouseEnter")
    End Sub
 
    Private Sub Panel1_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles Panel1.MouseHover
        Debug.Print("MouseHover")
    End Sub
 
    Private Sub Panel1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Panel1.MouseMove
        Debug.Print("MouseMove")
    End Sub
 
End Class

thanks
