The instructions were very sketchy. I tried, and didn't see any effect, so I closed that particular file and went on to something else.
Well, I guess I did SOMETHING, because now those effects seem to be permanently stuck ON. I've tried everything that I can think of. I even deleted all effects from the Actions palette (apparently you can restore the defaults later.) No effect!
The effects that are haunting me are "rippling water" and a shadow. Also, if I click anywhere in a .gif with the text tool, instead of creating a new text layer, it "highlights" the entire image.
What can I do?
Okay, I now appear to have a .gif problem! I restored my original Actions palette, and somehow that seemed to take away effects for .psd and .jpg files. However for .gifs, this is what happens:
If I open .gif file, the text has the effects.
If I CREATE a brand-new .gif file, I still have a problem, but of a different sort! The text is greyscale and the background is coral! No matter what!
And of course, once applied and Saved and Closed, you can't undo anything. There's no turning them on and off.
As Ed said, if you aren't working with layers when you apply any action, it's permanent unless you undo it before saving and closing the file. The same holds true if you are working in layers and the action you apply is not to a smart object layer.
If you're just messing around trying to find a look you like, it's always a good idea to keep a copy of the file you're working on in a different folder.
