When the icons are used in the Forecasts Skins they have a grey background. When they are used in the Tray Tooltip they have a white background. How can we control that?
Those images are PNG’s with transparent backgrounds. If you have IE 7, they should be displaying with transparent backgrounds in the forecast areas.
The tray tooltip image is not able to handle PNG transparency. White is the default background color when no color is specified (which is what I am doing). The background color could be matched to the background color of the tray tooltip window. That would really only work out well if the tray tooltip background was a solid color.
I don’t use IE 7. And have it on only one machine. Too sluggish vs IE 6.
