If you need help with this, you need to start a new discussion thread and indicate what you are having an issue with. A detailed explanation is best, working with one issue at a time.
@Yehuda, do not complain about things that are unimportant. The jar file was included so that you did not have to deal with altering the codes. If you insist on messing with the codes, that is your choice -- deal with it. There is no need or reason to mention here how difficult it is for you to change. It is not productive in any way.
@Yehuda, you do not have to open in greenfoot at all. Just download the GFAR file and extract the inner executable jar file (Transparencies.jar) from it. Then run that jar file directly.
Okay. Found the solution. After the 'super' call, you get the world canvas; immediately after that you need to place the following line:
worldPanel.removeAll();
I think you just need to repaint the background of the world:
getBackground().fill();
as one the first few lines after the 'super' call in the constructor.

The answer is essentially given in my response to Wasupmacus's question. The GUI control frame (where the Reset and Run buttons are located) limits the width of the applet.
