I have added a second monitor and am now working in a multi-monitor display (in Windows 7). I have a constant problem with window focus, where I'm looking at one monitor, doing something with the keyboard, and failing to notice that the actual focus is on another monitor.
The example scenario is like this: I am editing a file in monitor 1. Then something happens in monitor 2 and I respond to it and move the focus there. Then I start thinking about my editing in monitor 1 again, and decide to close the window, and I press "Ctrl+W" to close the editing window - but instead the window at monitor 2 closes!
In short, I am moving my conscious focus between monitors, without moving the "windows" focus between front-windows in each monitor.
I am looking for a solution that will highlight (e.g. red frame) the monitor containing the currently active focused window. Have searched for it but to no avail, and all help would be welcome.
