TFT Smudge

I have a 15 TFT on my IBM Thinkpad A31 laptop running Windows XP and have noticed other than one dead pixel (which is fairly common I gather) a dark smudge which only appears when viewing light colours in the centre on the screen (in the shape of a dark line about 1cm wide and 5 cm in length).

I have a 15" TFT on my IBM Thinkpad A31 laptop running Windows XP and have noticed other than one dead pixel (which is fairly common I gather) a dark smudge which only appears when viewing light colours in the centre on the screen (in the shape of a dark line about 1cm wide and 5 cm in length). I have tried the obvious (eg. cleaning the screen) but the smudge is still there. I have noticed this in the past week and it hasnt been there since I got the laptop 5 months ago.
 
Is this a problem with associated TFTs or something faulty?
 
Many thanks

P.S. I have also noticed strange ghost images that appear only on the explorer/IE toolbar for some reason. They look like several lighly coloured blocks which are to the right of the icons on the toolbar. I have not applied any skins and am just running standard blue 'lunar'. Again I have only recently noticed this. Any suggestions on why this is happening also?
