  Thanks for finding that!

  I'll be sure to do that in the future, and I'll try to run over the code and
sort out the other instances of this that I'm sure snuck in.  Probably they
should all be fixed if this is to be uploaded for potato, and it should be
fairly easy to fix, I hope..

  The UI code is currently in the throes of being almost completely rewritten
for the next release.  (branch "ui-rewrite" in CVS, which doesn't compile
yet..)  I'll try to deal with this problem at the same time, but for now you
can just press "q" :-)
