I occasionally get a message as my asus netbook boots up asking if I wish to set filter keys yes/no/. To date I have tries yes / no and ignore by closing message box down. The issue I have is that every time this message appears the machine refuses to recognise my password. I have to shut down by holding off button . Then I can restart my machine and login without any problem. Has anyone else ever had this problem? Is it something I can stop being concerned about? My worry is that the problem will one day become permanent!
