Well, here is one for the books. No damage done, but about as strange as it gets. I was up late tonight using the computer with my logitech wireless mouse. I hear this snap noise, and this sputtering hissing noise. I went to grab electrical cords thinking a Power supply let loose in something. I could not find the offender but kept listening. The noise was coming from the wireless mouse! It still had the LED showing on the bottom, but it was flickering some. I thought to my self, how and the hell could a mouse with two AA batteries make a noise like that? Well, took the battery cover off. closer inspection showed that one of the duracell procell battery's had Grey goo hissing out of the positive end of the battery. I have NEVER seen a AA battery do that before. replaced the battery and the mouse was fine. Go figure... They were some i had laying around with a 2008 code date on them.
