Hi, I just ran into the same thing reported by Bo Peng a short while ago
-- if in math you make an explicit superscript but also append a "'" as
a shortcut for prime (= matrix transpose sign here), latex complains
about double superscript. Minimal lyx file is embedded below, but I
guess only \begin_inset Formula $a^{*}'$ actually matters.
I know how to workaround, but I read somewhere that lyx tries to produce
correct latex files (absent any ERT). So, is this a bug by official
standards?
