Also, in my experience, the screen's corners darken whether the BL is on or off. I've not noticed the screen becoming hot with the BL off, but it's possible I suppose. >But I've put a Picture of my screen online. So you can see what I mean. >http://www.webkreativ.de/temp/pb540_lcd.jpg Sadly, that's what we are all seeing to various degrees. It does grow in the corners first, then spreads out along the sides. I had set up a maxed-out 2300 with a 280 screen, hoping to have the perfect travel 'Book but 'twas not to be. : -( I've got a 'new' 250, I haven't run it yet for a long period so maybe now is the time to see if it afflicted. I'll report back if I learn anything new. Dan K -- PowerBooks is sponsored by <http://lowendmac.com/> and...
