This question already has an answer here:
Currently, on Windows, if you click an app in the taskbar, it is brought to the front of the desktop.
However, if the app is already at the front it is sent to the back of the desktop, i.e. hidden behind any other windows you have open.
I would like to turn off this second feature so that when I click on a app it always puts the app at the front, even if it is already there.
I realise that this is how Windows has always worked, but I use a lot of instances of the same application and would like to be sure that when I click on an applications taskbar item, it will be at the front. Even if it is already at the front.
From my experience Mac OS X and Ubuntu both already do this by default. Only Windows hides the clicked app under these circumstances.
Example: To test out what I mean, open a few applications on Windows and make them all full screen. Then keep clicking on one of the taskbar items. Do you see that the app appears, then disappears, toggling visibility.
Notes: Just to clarify, the appearance of the taskbar itself is fine. I never group my task bar items and use TaskbarTweaker to stop aero peak preview etc. The thing I have a problem with is that clicking on a currently focused taskbar item, hides the app it represents.
