Dear all, It is confirmed that if the .bst file is in a path without space, the bibliography will be generated correctly, even if lyx is installed under c:\program files\lyx. So,
1. It is safe to install lyx to c:\program files, 2. It is not safe to put .bst files in a path with spaces. .lyx files and all figure files are OK, as well as .bib files. Bo
