Normally I am pretty tech-friendly, but this is just boggling my mind. I just upgraded to 10.7 last night and I'm having a couple of issues with the OS. First thing is that when I use the scroll wheel on my mouse, it's reversed. If I scroll up, it actually scrolls down; vice versa. Second is that everything is showing up in weird characters - attached the screenshot. Any help would be appreciated, it's quite frustrating. Thank you!!
