Not yet as I could not follow most of the instructions,limitations of the computer. The screen does not be centered especially, when the changed to This can be the menace.Another thing I meant to question is that I have already done a personal id sometime back and this has dissappeared. One of the steps I am supposed to follow ask me this question if I have my personal id.

Which steps am I supposed to follow, Internet Explorer 7 or Firefox 3?

Just tried Firefox but when I click into tool menu, it did not drop down instead there was flickering involving all menus. This flickering runs up and down all the menus so that I cant see or click. Actually, this normally happens when changed to and it happens to every window I open nd try to click at any manu. At times, when I am successful at clicking, I wont get what I click instead, it always roll down to the last item in the menu chosen.

Am using Kaspersky as antivirus.

hi, this is further to my earlier reply I called the text seal or "Are you protected" "personal id". I created this seal more than 8 months ago. Lately, I find the seal missing. Not knowing where to report to, I just hung on until, I saw the reply to my enquiry which mentioned the text seal, so I would like to hi-light this situation which could be the cause of all thats happening to my computer.
