How to change the frame size?

My friend was thinking about making a game. Fusion 2.5 automatically makes the frame size 640x480, but she would like it to be 800x600. When she changed the resolution in the storyboard editor, it looked like this:

When she tried to test it, it showed it in a smaller size. If an object is placed in the lower right-hand corner it stays outside of the frame. Could anybody help with how to change the resolution?

Hello!

When you change the Frame size, it doesnt change the Window Size.

You can change your Window Size by:

Left Clicking your application in the Workspace Toolbar > Then Clicking the Window Tab > Then changing the value there.
