Dear LyX Developers, I just updated my SVN copy of LyX and I have been playing with the new background compilation of documents. This looks like it will be a wonderful feature.
In the process of experimenting with it, I found a bizarre problem that I wanted to call to your attention. I am receiving a bizarre error when I try and compile multi-part documents with xetex (and in some cases pdflatex). The document will appear to compile, but then the PDF viewer won't be able to load it. No LaTeX errors appear (as happened using the old compilation system). It simply fails silently. If I load the "Progress monitoring dialog", the only error that it provides is "Error previewing format: pdf4" I have already checked the file handling for PDF4 (xetex), and it is correctly set to okular. I tried previewing the file with Adobe Acrobat, but that provides the same error. If I remove all of the child files (with the exception of one), it no longer gives this error. Or if I compile a document without child documents, it will also successfully show the document. I tried experiments with pdflatex and regular latex and was not able to replicate the issue (though these documents were very short and there might be a problem with length). I have not been able to determine any other patterns that might help with locating the bug. Also, the same file compiled without any issues last night (prior to updating the source and recompiling). Please let me know if I can provide any additional information. Cheers, Rob Oakes
