Cannot add attachments to email
I have had NIS for Mac for years. When my subscription ran out last week, I decided to get Norton for free from my internet provider, Comcast, rather than pay for another year. I didn't change any settings.
Now, when I use my web-based Yahoo email, I can no longer attach anything to the email. This happens (or, rather, doesn't happen) in both Safari and Firefox.
Since the only thing I've changed on the computer is getting Norton from Comcast rather than directly from Norton, I tend to think Norton is the problem. And, if Norton isn't the problem, I need to know that, too. Otherwise, when I try to email Yahoo, they will blow me off with a stock "it's not us" reply. As it is, I have a feeling as soon as Yahoo's computer sees "Norton" in my question, I'd get a robo-response.
Because everything in Norton is written in computer-ese, I do not understand what any of it means, so I can't tell if I am somehow blocking the attachments from getting attached.
My computer is an eMac, OS X10.4.11.
