See the START button on laptop screen!

The default size of the 'decode from camera' dialogue extends off the bottom of the laptop screen (common resolution 1366x768).
Please rearrange the "Start" "Stop" and "Exit" buttons so that they are visible at this resolution - so that all of the 'decode from camera' dialogue is visible on typical desktop settings.
This may be by putting them in the empty space top-right of the dialogue, or by shrinking the dialogue to less than 768 pixels tall including the title bar and camera viewport.
