I'm having issues when trying to click on a link on a webpage or pop up. Firefox and Safari are not registering when I click on a link or button. I've only been using a Mac for only about 5 days now so I don't know all the settings and what they do. Also this was working two days ago. If there something I disabled or enabled, how can I fix it or re-trace my steps. This would be a big help since I need this to download PSD's for my artwork.
