Has this ever happened to you? You’re merrily typing away in some application, minding your own business, when– suddenly– a dialog pops up and steals the focus from you.
This is the single most annoying – and potentially disastrous – thing any application can do.
Spaces is one of the worst offenders. Not only will it switch windows when an alert comes up, but it will completely switch spaces and pull the current application out from under you. I really want to like spaces, but it keeps annoying me by switching on its own when a window in another space demands attention.
