"Burn In" on TFT Display?

["Rainer Feuerstein" <thinkpad@bedrock.mayn.de>]

A few minutes ago I recognized a "shadow" in the upper right corner of my display (12.1" XGA 
TFT) that shows the Win NT controls (Min., Max. and Close Button). I only saw it because I 
accidentally moved a window with grey background out of the upper right corner of the 
desktop.

Is this really a "Burn In" like old monitors had?

What can I do against that? I use my TP the whole day long and I can't run a ScreenSaver 
while working. The Win Controls are at the same place all the time of course, since I usually 
work with maximized windows (even then MS Visual Studio is too small...)
