No messages appear on my terminal (LyX svn on Debian Linux started from x-terminal emulator). Do the messages appear: * when typing the commands in a math-box * when selecting the text \mathrm{K}^{+} and converting to math with Ctrl-m * when opening a file containing this math, or * when compiling? Maybe a minimal example file could help further (e.g. to see whether it is not *missing* a package but *using* a package that creates the problem). Günter
