So, in CS6 Adobe introduced a new back panel in all their products (Ps Ai Dw Fla etc).
I suppose their intention is to contain everything (tools, images, whatever...) inside it but i find it so frustrating: this panel hides desktop or other open applications so i have always to double click it to put in the dock and have access to other resources.
How can i set CS6 to have a CS5-like inteface?
In photoshop go to Window and uncheck the Application Frame.
The other cs6 applications might have a similar option.
The Application Frame was actually introduced in Photoshop CS4. It's just on by default now in CS6.
