There are a few errors with CorelDraw7.
The following items will crash it:
Layout menu ->Object manager, Layer manager, Graphics and Text Styles,Color Styles.
Tools menu -> Browse, Clipart, Photos, Favorite Fills and Outlines.
Also, the windows that get opened that are titled "Group" do not have an obvious way to close them. To do this simply right click in the small gray area just below the title of the window. Then select "close all". If you can't get the menu to appear, make sure you are clicking as close to the top of the gray area of the window as possible. I also got the boxes to close by crashing it with one of the above items.
