UI_error_message not working?

[Knight Captain]

I cannot seem to get the UI_error_message to appear on screen. The only place I've seen it work is in the Beta when leaving the Knight's Test. Is this the correct use?

UI_error_message("text to appear");

It appears this was used so play testers could immediately see something was wrong, and so would be very useful in writing new Usecode. It can be seen in SI+SS if you start a new game, set gflag 4 and then use a Jawbone with a Tooth on a Serpent Gate. The only output is in stdout.txt as described in the documentation.

UI_printf looks more advanced than I immediately need, and does not appear in the original Usecode.

I'll have to take a look, but it might be a few days.
