I sent my acer one to acer in Texas to hbe reformatted. It came back a couple of days ago and I can't get the menu that I used to get when I right click on the desktop. Without this I can't get at a lot of programs including "add and delete programs". The other problem is one I have always had. when I try to add a program it says that there is no room on the disk.The file manager says that there are 5.3 gigabytes free on My Disk but most of it is apparently on the 8g SD in the left side slot. In other words it is not integrating the left slot SD card. I am really new with linux and struggling. I called acer support and after an hour of being on hold the "techncian" said that he couldn't help me. They weren't trained to know that stuff.
