As your program moves through the source code, the PPO window will change to reflect the pre-processed output for the source code.
If you move or re-size the PPO window don't forget to save the changes, otherwise the window will return to it's original place the next time you run MrDebug.
The following is an example of the pop-up menu for the PPO window, which may be summoned either by clicking the right mouse button on the window or by using <Alt-F10>.
