How do I stop windows from promoting themselves to foreground?

Hi All

Does anyone know how I can prevent background windows
from promoting themselves to the foreground and stealing
the focus?

Essentially, I want to prevent any window from being
promoted to the foreground unless I click on it in the
taskbar (or Alt-Tab, etc). Is this possible?

For example, when I click on a link in Explorer, the page
starts loading, I switch to another window and type
something else, then in the middle of my sentence the
Explorer window makes itself the foreground and the
second half of my sentence gets lost. This drives me
nuts. It's especially bad when (eg) I'm typing in a
password to log on to a website. It happens with all
applications, not just Explorer.

Cheers
