That's really weird. Sounds like a bug in Allegro (or, more likely, a bug in Windows which Allegro trips over). Sorry about your icons! I'll see if I can reproduce this on my computer at home and if I can I'll report it on
www.allegro.cc. Thanks for letting me know.
Ah-har. We meant in the game.
You don't need to edit the source or recompile or anything to use Tourist mode, you just need to add a line to the init.txt file.
