That's called Stealing Focus. There is a setting in the registry that you can change to try and prevent this, but there is also a well known and recommended utility that will do it for you if you are not comfortable with changing the registry. Personally I would use the utility.
The registry option;
The utility is TweakUI from Microsoft's PowerToys for XP, available at;

Hello, I would like to know if there is a way to change this setting- Win XP, 2002 SP3, IE8
Let's say I open an IE window, I am looking at something on it, realize I need a 2nd IE open, click on it, then click back on first one. I think I am typing on the first, but in the meantime the 2nd had come to the foreground. It could even be using Excel first, then opening IE, the 2nd, 3rd, etc always pop up in the foreground. Please tell me I can change this. Thanks!
