Why do I always have to resize the UI?

I know I can stretch the window so I can see more of the budget without having to scroll as much BUT after I close it, and then have to re-open the app Cashculator returns to the default size, making me either scroll more than I want to or stretch the window again! I don’t like going to Full Screen because that’s too big.

Does your document reopen in the same screen/view as you left it or does it also change when you reopen?

Also, in System Preferences, Desktop & Dock, what do you have in the highlighted area? If any of the switches is different, it may behave differently since they control window restoration, as far as I remember.
