This of course possible. I found the error. Remove the line Input obsolete.inc from thmamsarten.layout, and it should work. obsolete.inc did not exist in LyX 1.3 either, but LyX 1.3 silently ignored missing includes, while LyX 1.4 complains. Unfortunately the error message "Cannot read layout file `'." is not very helpful, this needs to be improved. Georg
