GUI using Dll 'Background[Color]' parameter doesn't work

[Krakatau86]

I'm using 1.1.30.03-H001(Ahk_H Unicode 32-bit) Autohotkey.dll with C#
Gui, Add, picture, x100 y100 w100 h100 vGui_Img +0x100 backgroundtrans, Img.png

GUI using Dll 'Background[Color]' parameter doesn't work
And, if Script reload it self(inside script), GUI shows different(fontsize & styles ...) unlike the first run.

[HotKeyIt]

Can you test with latest version and show a full example?
