Hi, I tried to use the \underrightarrow Frame decorator from the math-panel inside of a display formula.
Lyx shows the arrow correctly but latex just
stops with the following error message:
-----------------------------------------------
Undefined control sequence.
A\underrightarrow
{trans}B\]
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.
-----------------------------------------------
Is this a bug in my latex backend or do I need
an extra package?
I'm running lyx 1.3.4 on a ubuntu/warty linux box.
A tiny test file showing the error is attachet.
Regards,
Johannes
