I dont think thats what he means.
For example, when you have aim up and you’re working on something in say PS or Lightwave, and you recieve a msg on aim, the window pops up and steals focus from your work. You could be in the middle of typing, or some other thing (clicking and moving points or something) You end up either typing stuff intended for a diff window on your buddy’s aim msg insted of your work.
As far as I know, nvidia’s drivers have something to handle this (kind of) … it allwos sloppy focus, allowing the focus to follow the mouse cursor. Alternativly some programs have the ability to turn thier focus stealing off (aim) but not all
You could also try and download tweakUI (assuming you have 32bit Windows) and see if that has any options for this problem.
