I love working with multi-monitor systems (see “Go, multiply and detach: Multiple Screens with Eclipse“), as this extends my working area. So I decided a while back to install a multi-monitor system on my home desktop too, as this is such a productivity boost.
But with moving the laptop machine between the display configurations, it happens that an application opens ‘off-screen’, and there is no way to ‘grab’ it with the mouse 😦
