Any way to keep windows from pushing themselves to the front?

[quote PeterB]This has bugged me too, big time, because especially on older (slower) machines, the new window popping up -- you end up clicking on something you didn't want. So I too would like the answer to this. And also-- I'm not running Leopard; I'm running either Panther or Tiger... so this is an across-the-board OS X problem.
And if you use a lot of key commands, you end up closing windows, renaming files, sending emails, hitting cancel... all on things you didn't want to.
