I'm using CS3 and have a project with many layers. When I have a layer selected (not the background layer) and go to apply a filter, most of the options are grayed out. I can't get to artistic filter or brush strokes or sketch, etc. If I opened the file separately, as in not adding it as a layer to my main project, all the layers work. None of the layers are locked. Why is this happening?
Thanks so much,
