Foreground to transparent gradient filling to solid foreground color

[annm38001713]

I am trying to do a simple white to transparent fade over a grayscale photo (so that the edge fades to white). I picked the preset Foreground to Transparent with white as my foreground color, but it fills the entire window with solid white. I've tried with different foreground colors, tried using the legacy preset, tried doing a black to transparent mask, and nothing seems to work. The gradient tool always fills the entire window with a solid color. This used to be a 2-second maneuver but it's taken me all morning so far...

It may be a silly question, but are you sure you're doing this on it's own layer?

Might want to check the little box that says, "transparency" after you confirm your gradient type in the gradient editor box. It's on the top bar  (at least the way I set mine up) next to Mode, Opacity, Reverse and Dither.

Can you post screenshot with entire window and Layers panel visible? Gradient tool should be active.
