Thanks Jim, Marlyse, and Wayne. I now have it working in Safari 1.2, yeah!
But even with doing both recommended procedures, it's not working in Netscape 7.1. The infernal Netscape mail app takes command every time. Anyone else using Netscape 7.1 & Powermail 4.2.1 and clicking a mailto link and having it open into Powermail? Or selecting Send Page, and having it open into Powermail? (I guess I might have to more up the timetable for my transition into Safari 1.2?) Thanks, so long for now, TOM >>Has anyone been able to successfully configure Netscape 7.1 or Safari 1.2 >>to use PowerMail 4 as the mailto App? >> >>If anyone knows the config procedure, I'd appreciate it if they would >>share it.
