@danpost Seriously! That's what I did, now I come here and see that's what you tell me to do (now is the first time I'm on the website ever since my last comment). I figured that every time I press reset I still have the same JPanel so I just keep on adding more things to the same one - until I exit Greenfoot.

How can that work, we're not dealing with drawing colors onto the frame/panel these are Components, if you try clicking on one of them it will work like it should. (It didn't work.)

So what do I have to do to make only one set of Components appear (making the frame bigger just makes more sets visible, making it smaller makes my one set not fully visible).

What's the difference between mentioning that you told me to try that and giving you credit for the fix? Giving you credit is mentioning that you gave me the fix. (I did thank you for it.) I still have a question in the discussion which you didn't answer (you only answered Wasupmacuz's question).

There is a bug with the timer it doesn't fully reset when "Cancel" is pressed. I'm in middle of fixing it. Please report bugs, comments, questions, or complaints.
