Recently, I noticed an irregular vertical bar on the left side (about 1" from the edge of the screen...it is darker in some places and lighter in others and very irregular, almost like a stain) of my 2007FP screen.  It is translucent and I at first thought it was image memory that could be cleared by leaving the monitor off for a couple of days.  I tried and it is still there.  It is visible in the mid range (gray, MSN background blue, etc).  Except for one dead pixel, the monitor has been fine.  The bar is driving me nuts, though.  Has anyone else seen anything like this.  I tried taking a screen shot of it, but it did not reproduce in the shot.....Thanks for any help, input, or commiseration......BIll G
