I use scottrade's sreaming quotes to watch my stocks, so I leave like 6 windows open in the exact same spot for hours each day. I've noticed when i close all the windows I can see dark spots where the windows were. The chart windows have white drop-down boxes on black backgrounds. where the white was, is where the dark spots appear. Exact size of the drop-downs. they seem to go away after a little while so far, but im worried about the future... I thought LCDs were immune to this? Is this thing defective? My Fault? I believe its a late model version.
