View Full Version : Screen Switching Problem Lion

Jul 18, 2013, 08:49 AM
I just noticed last week when for example I'm viewing a site, I have an app opened like Photoshop as well but the browser is the selected window.

The screen suddenly shows the photoshop window for half a second. And it happens like 10 times a day max.

I'm using macbook air 2011 connected to an external monitor. Could it be a software update problem? Or the monitor ?
