Here you find some basic informations on the script debug screen.
You can move all windows. Left click on a window header, hold the mouse button and move the mouse.
You can resize the windows too. Move the mouse on the border of a window. When you are in the right position, the mouse cursor changes to four arrows. Now, click and hold the left mouse button. When you move the mouse, the window size will change. When you click on the left or right side of a window, only the width is changed, when you click on the top or bottom side of a window, only the height is changed. Click on a edge to change width and height at the same time.
You may also close any window. You might don't need them in your current debug session. Simply click the close button on the right side of the window header (marked with a little 'x'). To re-open a closed window, right click anywhere to open the context menu. There is a option 'Show', that has a sub menu. Here you find any closed window. Simply click the window name and it will re-open.
All windows have special options in the context menu. To open the context menu, simply right click the window.
