LyX ⇒ Issue with tufte-report class (new in 1.6.6?)

[DaveG]

Hi,

I started using LyX last September and love it.

I just upgraded my Windows (XP) install - MikTex to 2.8, & LyX to 1.6.6.1.

I am writing a document with the tufte report class (v 3.5) and it fails with a message that the
\title{my great paper}

(LaTeX Error: Missing \begin{document}.)

I have also rerun the tufte-report example from the install and I get the same message. This leads me to think something might be broken in the LyX 1.6.6 tufte report support.

Can anyone help? Just having the same issue?

Dave
