Hi Blind Dragon,
Thanks for the help and also to all those who one way or the other showed interest in my problem. Unfortunately, it didn't go away; as such i had to take the gruesome task to reformat my hard disk. However i really appreciate your efforts and only hope and pray that it doesn't re-occur. Not conversant with Vista at all; but I believe being part of this family, I will be able to combat future problems, before they become a headache. Once more, thanks for you time. Remain grateful!
