Not sure where one would even check this. I thought Active X was pretty much always enabled.

Try this: http://help.yahoo.com/l/us/yahoo/mail/yahoomail/settings/settings-28.html

As I thought, settings were already set.

Which is good. That's the default, and one surely does not want to be in the position of telling prospective donor, "This is a super secure donation, but first, please go to Security settings and make these few innocuous changes."

It's just a mystery, I guess.

Maybe all the big donors will be using Google Chrome.

You're donators would not have to adjust anything Chuck. Everyone sees your form just fine...except you. Don't live in Bermuda do you?
