All true.  I wonder how many people don't use the Clipboard just because
of misinformation like the one Chris shows.

>(I also did an example program for AmigaMail a long time ago.)

I used the code in AmigaMail to add Clipboard support to A-Talk III.
That code works like a champ.  If the source is still around somewhere
maybe it would be a good idea to post the clipboard source from
AmigaMail on the net.
