thanks!

in blender 2.82a when I press command s to save a file browser pops up. but in 2.83 when I press cancel, blender turns black and I have to force quit it. the same thing happens if I try to render. in 2.82a it pops up a window that is about 1/4 the size of the screen, but in 2.83 it pops up a window that is fullscreen and when I close it it crashes blender. I can't resize the window and the temporary window is set to new window not fullscreen. i can send a video if you like
