define your own captionstyle and everything works!
\newcommand\myCaption[1]{\small\refstepcounter{figure}%
\centering\figurename\ \thefigure :\ #1}
in the float (!) choose paragraphstyle standard instead of
captionstyle and write
\myCaption{...the captiontext ...}
myCaption is only needful for captions with special math-symbols
or special commands. counting of figure is continuing.
on the other hand it's possible to work with a trick:
run from lyx dvi-view once without your mathsymbol
\overrightarray. the dvi-output than works and every
dvi-update too, you can ignore the latex-error when you
insert now your math-symbol.
overline and tilde works because they are not build with
special commands like overrightarrow. \vec{a} works also!
