Screensavers, eh? How much more mischief can they cause? Plenty, according to David Thatcher:
Ha! I have a story to tell about screensavers. I was in Alaska, and went to optimize a friend's Packard Bell. I helped them load a screen saver that featured a dog howling at the moon. Well, I get a call several days later, their dog, agitated by the apparent presence of another canine in his territory, urinated on the computer. Destroyed his hard drive, had to clean off the circuitry with rubbing alcohol.
It looks like there might be an amusing screensaver mishap article to be had out of this. Send in those stories and we'll have a look.
