Why? It is only a image button and i use for the image button a picture (gif) with transparent color. It is not a special code or somethign like this.

It seems that the background color for the image is set when the button is added. to work around this, when the background color is changed, re-add the button image. Since the button has the same name it seems to work just fine:
