Hello, It seems to me that boxes with simple rectangular frame does not allow for page break within the box. Instead the box moves with all text inside to the next page.
A box with more text than can fit on a page results an error: > ! TeX capacity exceeded, sorry [input stack size=5000]. > > \font@name -> > > \T1/cmr/m/n/10.95 > > l.94 \end{minipage}\end{framed} LyX 2.0.0beta3, OS X 10.6.6 Peter
