ok, here it comes ... not easy, but it's what you want ;-)
now \mybox{the lyx formula}
gives a boxed formula with a optimized frame. the value for \parbox in
\newcommand\myBox ... is no more important, but don't leave it blank,
latex needs a value. i choose the tex-code from fancybox.sty where
the Beqnarray is defined.
