A computer windowing system does not model real windows, it models pieces of paper, spread across a desk.
On a desk cluttered with papers, you can see bits of some papers and others papers are hidden by other papers that are on top.
There is no way you should be able to patent such an obvious real world, real life experience, just because you were the first to take that real world experience and replicate it on a computer screen.
All you have done is modeled a real work experience.
No! A digital window is not a complex enough system. It would inevitably exist given the hardware allowance and capability to multi-task apps. It merely frames an application or any number of objects within the "parent window" which is your computer monitor.
Frames, boxes, panels, or "windows". A child could come up with the need for a digital version of a container if none existed. The name that catches on to describe that container is irrelevant.
In the digital world we need to be sensible about what would inevitably exist given the hardware allowance for such an obvious software feature. Slide to unlock is child's play.
