Really? Mine came on when I first turned the board on, before I had written a single line of code.

I believe the OP's father meant that putting the board on the computer case may cause a short between the solder joints on the back of the board. I would point out that antistatic bags are slightly conductive( that's how they do their job) whereas computer cases are painted so moving the board from the computer case to the antistatic bag was actually going from bad to worse.

Yeap, that's the test program running. I assumed Sherlock-holmes2 overwrote it.

Although true, I often use my mcu's on anti-static bags without a problem. I like to program my bots while stretched out on the carpeted floor with a pillow, so gotta put it on something :P

You probably weren't working with CMOS circuits and MOSFET transistors. The old-school BJT transistors and TTL circuits are much less susceptible to ESD damage.
