Hi it is possible to navigate around your computer wihout the use of the mouse. If you use the tab key on your keyboard you should see a faint square appear around a selected icon on the desktop. Once you see this you can use the cursor keys on your keyboard to move from one item to the next. To use the right click you need to use the key which is to the right of the windows key which is on the right hand side of your keyboard and again anything you need to navigate around just use the tab key again. I also have a similar problem on a windows me machine which i'm fixing from someone but the os is not in a good state so I know this is down to that as i've reinstalled the drivers countless times without success.
