This is probably old, is known, but will never be fixed. But it's damn annoying.
I'm trying to let Minecraft make a random-generated level so I can convert it to be used in my Mynecraft server.
I'm very, very picky in how the map looks, so I need to constantly do a new map until I get one that would be a good candidate for what I have in mind.

However, World of Minecraft apparently doesn't like this and disables my hacks after generating just one map, making it quite difficult for me to survey the map to see if it's good enough with World of Minecraft's flight mode.

This probably will never be fixed until Notch releases a new patch for the Creative mode. But there has to be another way to do this.
