I would agree to examine the styled wall issues. There are now so many different ways to set attributes for walls as well as different types (textures can appear similar to fills at times) it has become very confusing and unwieldy. You need to check through the attributes palette, the classes dialog, the wall styles, the component styles and I'm sure I've missed something or two. The defaults (checkboxes) in these various places also tend to override each other. I have to resort to trial and error through all of them to find the right checkbox when something doesn't behave as I think it should and yes it can be very frustrating. VW's bills them as features and flexibility though......
