Try to put explicitly some displaystyle{} in a math formula
("explicitly" means : without using the math-size feature in the
mini-buffer).
Look at the dvi file : it looks good.
Now :
save, exit LyX, fire it again ...
no more displaystyle{} !!!
Defining in the preamble something like this :
\def\DS{#1}{\displaystyle{#1}}
allows to get round.
Is it really a bug ? Or do I miss something ?
