Hi, I'm a new user of LyX. I use Windows XP and LyX version 2.0.0.
When trying to use \underset or \overset (for instance, \underset{\lim}{t}
both with the command in latex and using the button in the frame
decorations menu), I get the following error message:
$\underset
{t}{\lim}$
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.
I'm sorry but I don't understand the message. I have also the same problem
with the \overset, \underrightarrow and the \underleftarrow,
\underleftrightarrow commands too, but the rest of frame decorations seem
to work fine.
Thanks for your time,
Maxim
