I gave up on Safari a long time ago. With Mac's OX-10 it doesn't do a lot of things you'd think it would. For example it formats this forum differently and won't allow the attachment of photos to a post even though it displays the photo posting function. Firefox, on the other hand, does everything it's supposed to do and I've never had a problem with it (the same holds true with all my co-workers who use newer Macs). The problem that prompted my first post in this thread was I accidentally opened the forum with Safari.
Interestingly, the spellchecker function that works so great with Firefox does not appear with Windows Explorer, which is what I'm using (on a Dell) to send this message.
