Hallo,
today I found an error in opening an older text with LyX:
The commands "\quad\begin{array}" and "\vert\begin{array}" are saved and
exported as "\quad\begin{ array}" and "\vert\begin{ array}" which give LaTeX
errors.
In all other places, "\begin{array}" is placed after an empty space or a
\left-bracket construction, which are correctly saved or exported.
As workaround, I added "\left ." and "\right ." around these both array
environments.
I tried the file with the newest cvs-version and with the version from
September, 25th. Both have the same behavior.
