Tut tut, don't you know not to smoke in the machine room, nor eat food at the computer? ;-) I can't say that I've actually come across a dirty CD/DVD laser, yet. But I've come across plenty of PCs where just about everything, inside and out, has been coated with filth. Houses with open fireplaces seem to be the worst, you get this really sticky residue that'll hold onto anything that floats in the air. Makes me wonder if they're like valves in gear that's used a lot - the operating heat burns off the small amount of dust that lands on them while off, and the slight thermal draught stops dust landing on them while working. -- [tim@bigblack ~]$ uname -ipr 2.6.23.12-52.fc7 i686 i386 Don't send private replies to my address, the mailbox is ignored.
