Issues with my materials

Hello,

I'll do my best to explain my situation.

I have a custom Code Set Style. When I go to edit a render material in the code set style I pick the symbol next to the current render material. The "Select Render Material" box opens, I click the pull-down arrow and there is a limited list of materials available. I open my Materials Library Tool Palette and there are a bunch listed. I right-click on one, let's say it's called brick for example, and pick Add to Drawing. It says that the material already exists but I can create a copy. If I create a copy, then the material will show up in the "Select Render Material" box when I edit my code set. However, the name is prefixed with "copy of-". So even though "brick" was not in the list initially, now I have one called "Copy of-brick", but still no "brick". How do I get all the render materials from the tool palette to show up in the "Select Render Materials" box???

Any and all help is appreciated,

Thanks,

Phil
