I've noticed Safari 3.2.1 has a maximum z-index value of 16777271. It's been fixed in the nightly to be the max value of a 32-bit signed int (2147483647). I'm curious if anyone knows where the number 16777271 came from before the bug was fixed. It doesn't correspond to any data type I know of. Thanks. Eric Puidokas eric at puidokas.com
