I am using lyx version 1.6 on Windows XP. I want to use the ACM SIGGRAPH document class. It shows up in the drop-down menu for document classes but it's listed like this: "Unavailable:ACM SigGraph". This looked ominous but I selected it anyway and got the following error message: "the document class acmsiggraph could not be loaded".
What does this mean? How does lyx determine which document classes are available and which aren't? It seems strange that it would know this document class existed but would not allow me to choose it. Is there some easy way to make it available? -brian
