Mountain Lion has these new sharing buttons that I will enjoy to use if Facebook was released (not yet) and if the email is working properly. When I click those sharing buttons (for example, sharing a note), it gives some options, and those include Flickr, Twitter and Mail etc. But, instead of the Mail app stamp icon, it gives me a Chrome logo. I have Chrome installed on my computer but my default browser is Safari. So I don't want it to launch Chrome every time I share a file, I want it to launch the Mail app. I don't see a way of fixing this in System Preferences?
