John,
This is my second attempt to send this. The previous attempt was rejected
because the zip file was too large. I had included the SWT library in it,
which is what made it so large. Since you probably have that already, I
deleted it from the zip file and am going to try again with a much smaller
zip file.
Thanks,
Dick Baldwin
