A Bug? ShowDialog and Opacity and TaskBar

[dynamic_sysop]

erm when using opacity , 1 represents 100% to make say a 10% ( almost invisible ) you need to do 0.1 , eg:
in Form1 ( no need to modify the New sub in form2 either )

[COLOR=BLUE]Private[/COLOR] [COLOR=BLUE]Sub[/COLOR] Button1_Click([COLOR=BLUE]ByVal[/COLOR] sender [COLOR=BLUE]As[/COLOR] System.Object, [COLOR=BLUE]ByVal[/COLOR] e [COLOR=BLUE]As[/COLOR] System.EventArgs) [COLOR=BLUE]Handles[/COLOR] Button1.Click
        [COLOR=BLUE]Dim[/COLOR] frm [COLOR=BLUE]As[/COLOR] [COLOR=BLUE]New[/COLOR] Form2()
        AddOwnedForm(frm) [COLOR=GREEN]'/// add it as an owned form
[/COLOR]        frm.Show()
    [COLOR=BLUE]End[/COLOR] [COLOR=BLUE]Sub[/COLOR]

in Form2 :

[COLOR=BLUE]Private[/COLOR] [COLOR=BLUE]Sub[/COLOR] Form2_Load([COLOR=BLUE]ByVal[/COLOR] sender [COLOR=BLUE]As[/COLOR] System.Object, [COLOR=BLUE]ByVal[/COLOR] e [COLOR=BLUE]As[/COLOR] System.EventArgs) [COLOR=BLUE]Handles[/COLOR] [COLOR=BLUE]MyBase[/COLOR].Load
        [COLOR=BLUE]Dim[/COLOR] frmMain [COLOR=BLUE]As[/COLOR] Form1 = Owner
        [COLOR=BLUE]Me[/COLOR].Opacity = 0.1 '///0.1 = 10%
        frmMain.Hide()
    [COLOR=BLUE]End[/COLOR] [COLOR=BLUE]Sub
 
[/COLOR]    [COLOR=BLUE]Private[/COLOR] [COLOR=BLUE]Sub[/COLOR] Form2_Closing([COLOR=BLUE]ByVal[/COLOR] sender [COLOR=BLUE]As[/COLOR] [COLOR=BLUE]Object[/COLOR], [COLOR=BLUE]ByVal[/COLOR] e [COLOR=BLUE]As[/COLOR] System.ComponentModel.CancelEventArgs) [COLOR=BLUE]Handles[/COLOR] [COLOR=BLUE]MyBase[/COLOR].Closing
        Owner.Show()
        [COLOR=BLUE]Me[/COLOR].Close()
    [COLOR=BLUE]End[/COLOR] [COLOR=BLUE]Sub[/COLOR]

the Owner bit replaces the modified new sub eg:

Public Sub New(ByVal frm As Form)
MyBase.New()
pform = frm

^^^^ becomes...

Dim frmMain As Form1 = Owner
