Re: pdftex process on MAC OSX Lyx 2.0.0 - more
Jens, The process that is left running is called pdftex (not pdflatex), and its parent process is called Python, whose parent process is Lyx. That is the sequence of parent to child processes. In relation to what I inserted into the koma-let2.lyx template file it was simply a → inserted in MATH mode, not text mode. It does not matter what symbol you insert in Maths mode. To reproduce it you simply load up the koma-let2.lyx template, compile it as an initial test. It will compile, and if you look at the processes the pdftex process will have started with the compile, and then would have closed. So it no longer appears on the list of processes. Now add in in a symbol in Maths mode. Compile the same file but with only this symbol added. The pdftex process will continue to run once the compilation is complete. Quit lyx, and you will see the pdftex is still running and consuming 100% of the core that it is running on. You have to do a "Qui"t from the Activity Monitor to stop pdftex. The Python process )the parent of pdftex) stops when Lyx is exited. It would be a good idea in the future to make sure that Lyx closes all the process that it is responsible for, even if a process has gone rogue. Of course an error message is handy if this is occurring. Thanks for your comments on this issue.

Jens, It is not happening all the time with the system, but only under a very specific class file.

The 'pdftex' engine in PDF output mode (command `pdflatex`) does not support EPS graphics. The 'pdftex' engine in DVI output mode (command `latex`) does not support PDF graphics. If the argument to \includegraphics has no extension, it is added by the graphics package depending on the output format and available graphic files. LyX converts graphics to the required format in a pre-processing step - but not for ERT (using ERT you are on your own, this is a feature). > How can I solve that problem? a) do not use ERT for the graphic input command b) provide both, EPS and PDF versions and leave out the extension in the ERT.

On-the-fly spellchecker
Dear all. I have been using Lyx 2.0 (Windows 7) with very much delight. Nonetheless, there is a nagging problem that is more annoying than damaging. When the on-the-fly spellchecker signals a mistake, sometimes when you select the correct spelling, the cursor jumps to another instance of the mistake in the document. It is difficult to pinpoint the cause, as it is not frequent or predictable. It only happens every now and then. The document I'm working with is big and has many spelling mistakes (in Spanish). Have you seen this problem before? If you need more info, let me know how can I gather it. Keep the good work up. Regards. - Julio Rojas jcredbe...@gmail.com
