Removing style in slide
After applying a style to a slide, and then later removing the style using the "no style" button, the images in the slide still have the settings from the original style. It doesn't revert to origininal.
Right click on the slide you wish to remove the slide style. Select "remove," then select "reset slide." This works on a MAC. In fact, I can't even find the "no style" button you mentioned in your post.
Thanks for your answer the "no style " button is on the top of the style list. That is what I have always used to remove a style. I guess I have been doing it wrong. I will use your method. Thanks again.
