This is a challenge. My cursor seems to jump all over. When I'm typing in one spot, it jumps to another and continues there. Or, even better yet, if I'm typing an e-mail it will delete it and save it in drafts. This is a brand new Acer 5520. I'm not using an external mouse or anything and will be unhappy if I have to purchase something new for it. One thing it keeps doing is popping up the acer e-net management: internet is disconnected. It should be as I'm using a broadband. I'm 'bout ready to see if it floats or bounces better. HELP!
