I can reproduce as follows: 1. Start a fresh LyX session. 2. Open a new document. 3. Save (or Save As).
I get the following messages: Saving document ~/newfile1.lyx... Saving document ~/newfile1.lyx... done. Document ~/newfile1.lyx reloaded. (buffer-write: Ctrl+S, F2)Undo.cpp (515): There is no undo group to end here On a different note, shouldn't there be a line break in the last line after (buffer-write: Ctrl+S, F2)? git bisect leads me here: bbbc2b654175edbccb1ce54ae6dbb15f8a042360 which is related to this ticket: http://www.lyx.org/trac/ticket/8159 Scott
