Modifying portableapps client window to drop shadow

Hi everybody. Id like to know how I can modify the source of PortableAppsPlatform.exe with reshacker to make the window drop a shadow like every window in win7 does.

Some additional code here i guess:

object frmMenu: TfrmMenu
Left = 1200
Top = 394
AlphaBlend = True
AlphaBlendValue = 0
BorderIcons = []
BorderStyle = bsNone
Caption = 'PortableApps.com Menu'
ClientHeight = 573
ClientWidth = 406
Color = clGreen
TransparentColor = True
TransparentColorValue = clFuchsia
DoubleBuffered = True
Font.Charset = DEFAULT_CHARSET
Font.Color = clWindowText
Font.Height = -11
Font.Name = 'Tahoma'
