With LyX 2.2.1 I experience a strange behavior when trying to reuse old preamble-code in newly created documents.
Steps to reproduce. Open a new document and then an old one, open document settings for the old doc, mark a string in the LaTeX-preamble, copy the string into the clipboard buffer. Now switch to the new document, open settings and try to paste the contents of the clipboard. Nothing will happen. (I made extra sure that the preamble-window-box is active and accepting intput) The buffer contains the copied string and it is possible to paste it in external applications and also into the regular lyx-text-editor. (And after pasting it into the text-editor of lyx it will also show up when pasted again in the preamble, so this is also a workaround? It will not be pasted into the preamble if it is only pasted in an external application.) This is on Mac, OS X 10.10 greetings Mike
