Is there a way to use A4 paper in Tufte book class? The Tufte-LaTeX def file is prepared for A4. LyX is using Letter now by default. I used A4 without problems one year ago in LyX 1.6, but in 2.0.0 the option "Format" under "Document Settings - Page Layout" is greyed out. It does not make a difference if I set the default paper size to A4 in "Preferences - LaTeX".
Kindly, Roel Schipper
