How do I fix project 64 screen size?

By mistake the first time I started project 64 i clicked ';Full Screen'; but now I realize i just want the original smaller screen. But now everytime I open it its now in this narrow box on the upper left corner of my screen, its so weird and aggravating because i can only see half of the screen and so far I have no way to change i. Please, is there any way to fix this to either move the screen or change the size of the screen back to its original size? Please and thanks.How do I fix project 64 screen size?
