I start using Photoshop, and I find that it'll automatically start keeping settings I didn't tell it to. For example, only once I told it I wanted a shape with just an outline, but no fill, and now every single time I want to create a shape, it automatically defaults to a shape with only an outline. I never set it to automatically do this. Another thing, when I set the text to go vertical, it'll automatically set the default for text to go vertical.
How do I stop this behavior, and if there's no way to stop it, how do I set the tool presets back to default?
