I recall a partner in a CS class who changed my setup to focus a window on mouse over and that was really handy for programming with a ton of terminals open.
I've seen Dwell Click under accessibility options, but that doesn't seem to do anything. I know that sometimes the GUI control applets have features undisabled that don't really do anything (i.e. WINS) if you don't have the right stuff installed.
How do I get mouse over pretty much just simulate clicking the window.
