<aol>me too</aol> I've wondered about this for some years, Eudora 3.1.3 in my case. <snip> > >2.

Eudora is notorious for taking over all the clock cycles when it's in the foreground. I'm a little embarrased this didn't occur to me before. ############################################################# This message is sent to you because you are subscribed to the mailing list <[EMAIL PROTECTED]>.
