Hi, while search for those cursed files without layout (the modern version of headless knights), I found bug 666: http://bugzilla.lyx.org/show_bug.cgi?id=666
There you can find a file from David that uses amsart layout. After my latest fixes that involved to support older tabular format 3 the last missing :-) I am able to load it in lyx 1.3 and after some removals from preamble the file shows correctly. Wow. :-) This does not work for 1.4, apparently the Address style is deactivated in 1.4 but there is no replacement for older versions. Does the proper fix involves lyx2lyx? What should be done? -- José Abílio
