I clicked on the main menu and chose "View" then "Virtual Screen 1" then "Resize to 1440x900". Now everytime I start my VM it sizes my window to that size. If I try to make the window larger by dragging an edge it enlarges the window but my VM stays at 1440x900 with black bars on the top, bottom, left, and right. How do I undo the "Resize to 1400x900"?

By 1) changing the resolution from the Guest and 2) (more important) making sure that when the VM is running, under the View menu, the Auto-resize Guest Display setting is enabled/checked.

That worked. Thanks so much for your help.
