I need some software to stretch or scale a windows to fit resolution sizes.
E.g., I have a program that does not allow to be maximized or to change its windows size, that is 640x480. With that software I ask you, I would scale that windows and all visual elements inside it to fit resolution height or I would stretch any windows and all visual elements inside them to fit all resolution (1360x768).
So I'm searching for some kind of "sandbox" or "magnify glass" but that do not affect features of the program I want to resize, like network access, use of keyboard and mouse... i.e. I would like to see live video output from the stretched/scaled window (not a screenshot) and work in it (I could press buttons, type some text in edit boxes etc.)
Edit1: I don't want changing resolution, but only changing "scale" of a particular opened window...
Edit2: I "heard" that in Mac OS X and some Linux distros like Ubuntu 8+ you can zoom in some screen area pressing OS Symbol (Apple Key or Linux Key) and scrolling the mouse wheel. In Windows 7 I also heard about doing that with WinKey and +/- keys, but differently from Mac OS X and Ubuntu, you can only read the contents of magnified area, i.e., you cannot click in buttons, edit text or see animated images... if someone could show me a magnified work-allowed screen like Mac OS X and Ubuntu for Windows, I would assign the answer for him/her.
