I'm designing a windows app with MFC whose main frame window cannot be resized or dragged. The window is initialized to be maximized and remains so throughout it's use, refusing to be resized. It can be minimized to taskbar and restored. In essence, the app's window is full-time maximized.
The question is, would the average user find this type of design very inflexible? Would such design be frowned upon by the authorities of good design?
