Well, I better give you this patch then.  It's against 3.0.3 (I think).

Note: this is a fix to avoid a coredump - it's a kludge because I haven't 
looked into the reasons behind it yet so I don't know if something else is
buggy or just this.  Also, a couple of people - Andrej Borsenkow & Zefram -
have indicated another problem with the display which I haven't got round to
investigating properly yet; I can't reproduce it from their methods.
