Runtime Error

[Joe]

Every time I get my new e-mail messages (juno), I get "an
exception "Runtime Error" has occurred in Script" for
EVERY message. (I just cancel out of each occurrance)
I've been using juno for years, XP for several months,
but this just started recently. I keep Windows up to
date.

This is annoying!

Why does it happen?

How can I avoid it?

Thanks....
