When I walk away from the computer for a stretch and leave my timeline open, I get an error message that reads "file error: illegal name" when I return. This must be occurring when the project is auto rendering or something, because today I tried to do a simple slideshow using jpeg images and dissolves, and when I attempted to render, it gave me the same message. Does anyone know what is causing this? Could it be an issue with where my render files are or something? Thanks!
