Help with Window Sizing for Keyboard shortcuts

I come hoping for a solution! I am setting up Audition (again) and when I go to create keyboard shortcuts, I can see everything fine except, the size of the window is too large to apply. I can see "undo" and "clear" and that's it. I have tried everything I can think of but to no avail. The window won't resize. Changing the resolution does nothing. Please?
