The most common trick is to use standard FB windows
in place of Alerts, this allows you to *anything*.

As you've already woven your Alerts you won't like this suggestion
but keep it in mind for the future. 

In the past, when faced with this problem Chris Young (I believe)
sent me code to change the font info. It entails changing info in the
window record (an alert is just a type of window). I'll hunt and try
to find it, unless someone posts first - you see, i've just bought
myself a PB G3/266 and I'm still transferring FB to it, my sample
code is distributed over a range of other machines and backup
cartridges.
