okay so that worked very nicely for a minute - then i saved the file and
tried to re-open it.
Unfortunately lyx comes up with
Line ~116: Math parse error: Expected {. Maybe you forgot to enclose an
argument in {}
Line ~116: Math parse error: Unmatching braces
Math Panic, expect problems!
(that is re-typed so any typos are mine)
bummer
so I started munging about in the relevant section now it consistenly saves
as this
\begin_inset Formula \( \Delta vol=\frac{4\pi }{3}abs\left(
r_{pH2}-r_{pH7}\right) ^{3}=\frac{4\pi }{3}\left( 17.87\textrm{ }\AA
-16.03\textrm{ }\AA \textrm{ }\right) ^{3}=\frac{4\pi }{3}*6.263\textrm{ }\AA
\textrm{ }^{3}=26.24\textrm{ }\AA \textrm{ }^{3} \)
\end_inset
yes those \AAs were inside the {} before
and there was only one \textrm section per \AA
If I fix this in a text editor to
\begin_inset Formula \( \Delta vol=\frac{4\pi }{3}abs\left(
r_{pH2}-r_{pH7}\right) ^{3}=\frac{4\pi }{3}\left( 17.87\textrm{ \AA
}-16.03\textrm{ \AA }\right) ^{3}=\frac{4\pi }{3}*6.263\textrm{ \AA
}^{3}=26.24\textrm{ \AA }^{3} \)
\end_inset
it just reverts back with the next save (and no angstrom symbols are
displayed in dvi viewer (just spaces)
To re-interate
I can create a formula containging angstrom symbols which look fine in a dvi
viewer until i close and re-open the file.
After this happens I get the error mentioned above
In trying to correct the error i lose the angstrom symbols and something
funny happens when lyx saves the \textrm sections
does \AA not count as an argument?
thanks for any suggestions for how to resolve this issue.
