Problems with photoshop's outter glow/fade.

[N.T.M.]

I've been having a problem with photoshop. I've been trying to make a cd title (for stepmania). Now I figured I'd just make the graphics over a transparent background and give the image an outter glow. It seemed to work fine until I viewed it in the game. The outter glow didn't fade out. It just turned a solid color producing very rough edges.

Same thing with the text. I'd use the smooth option, but once in the game the faded pixels necessary to create a smooth appearance stood out with a rough white trim.

I even got other cd titles with outter glows, made slight changes, and then the same change occured. As soon as I changed a single pixel it f*cked it up.

WTF am I doing wrong? This is really annoying!!!!
