Thanks, I'll take your advice. In the meantime, I seem to have stumbled on the fix. I re-ordered my stylesheets in the same sequence they were awhile back and the error is gone (for now at least).
Any idea why this should matter? FYI, per instruction I found somewhere on the internet, all my stylesheets begin with '@charset "utf-8";' to accomodate my utf-8 encoding. Other than that, they're pretty standard.
