I am using Lyx 1.2.1 and am having problems with comments in TeX code blocks.
The issue is that latex2html requires: %begin{latexonly} and %end{latexonly} to be at the start of the line. However, Lyx 1.2.1 bundles all ERT into a single line, causing problems. I can tell because I did an export to TeX and looked at the output. The only workaround I have found is to add a hard carriage return (Control-Enter) in the ERT _before_ the comment. Actually, I can't put only a hard carriage return. I must have a space, then the hard carriage return. The comments used to work fine without the work around in LyX 1.X. -- Bruce Momjian | http://candle.pha.pa.us [EMAIL PROTECTED] | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073
