A strange problem about Alpha PNG

[hjyknight]

png01.png - the png file that I import, width 323px , height 494px
desktop.jpg - the effect after I apply the theme

and here are the parameters.
StartMenu > Pane > Basic > PlacesList > DefaultPaneSize:RECT:  0,0,323,332
StartMenu > Pane > Basic > Logoff > DefaultPaneSize:RECT:  0,0,323,54
StartMenu > Pane > Aero > Top > PlaceList > SizingType:ENUM:  TrueSize

My question is why the image is offset. Which property should I change?
I've tried to change the SizingType:ENUM property into Strech, but it didn't work.
Plz forgive my poor English.

StartMenu > Pane > Aero > Top > PlaceList > SizingType:ENUM:  Strech
StartMenu > Pane > Aero > Top > PlaceList > SizieMargins:Margins: 0,322,440,0

Now it looks like

StartMenu > Pane > Aero > Top > PlaceList > SizingType:ENUM:  Strech
StartMenu > Pane > Aero > Top > PlaceList > SizieMargins:Margins: 0,322,440,0

Now it looks like

I think it'd be easier to use if you add the blur back.

StartMenu > Pane > Basic > Top > PlaceList > AlphaThreshold:Int: 128

I found after I changed alphathreshold to 128, the image looks like mosaic.
