Hi all, I'm presently coping lots of tex equations into lyx and usually this works great, but this one drives me nuts:
\begin{align*} {\left( {\Delta ^{(1)} } \right)^2 = } & + \frac{1} {2}\left( {k^2 + \lambda ^2 } \right)\left( {Q_1^2 + Q_2^2 } \right) \\ & + \frac{1} {2}\left( {k^2 - \lambda ^2 } \right)\left( {Q_1^2 - Q_2^2 } \right)\cos 2\gamma \\ & + \left( {k^2 - \lambda ^2 } \right)Q_1 Q_2 \sin 2\gamma \end{align*} As with the other formulas I just copies it into the "numbered formula field", but this time it add an additional backslash, so the correspondig tex output is \begin{equation} \backslash begin \{align*}... So it didn't recognize the equations and escaped all keywords with backslashes, hence even in compiled output the formula is displayed as text... Any ideas? Thanks, Bernd
