Acer One 150 with 120 HD and linpus. I soon found out how to install new software and then went on to try out xfce desktop which seemed successful in spite of starting with faulty instructions. However I soon found that file manager was severely messed up. I therefore reinstalled the original system from the recovery DVD via a USB stick. But none of the 'more' arrow icons work nor the games icon. File manager is still virtually unusable (completely unusable without setting up menu on right click) and Media Player behaves in ways it was never designed too - probably other programs as well. Is it possible to achieve a clean reinstall? Any help appreciated. Paul Oates
