The worst thing I did involved color depth. I was trying to show off once at a place I used to work for how I could improve their website. ( these were the 3.1/95 days on their PC's) one of the computer was a 3.1 machine and I figured they need to see some of the photographs in better color so I tried uping the color depth only to have the whole display go all wiggly like an old timely scrolling T.V. set except worse! I tried and tried and couldn't fix it and boy did I take the heat. I've learned a lot since those days! You would think if the machine couldn't take it it shouldn't have the option!
