Kaisuo: Your status bar and fight menu remain because they are always being drawn in exactly the same place. When you use a CLS command, you are only clearing the current buffer, which in your case is the unseen backbuffer. Anything drawn to the backbuffer is invisible. When you call the Flip command, the information stored on the buffers is swapped over (from front to back and vice versa) so you can see the drawn image.
So using CLS wont erase anything you need in this case.
