buttons don't work

[Sartaj Syed]

Buttons defined in the constructor of a frame which is the main screen of the program don't work. There are two other frames that are registered as ActionListerners with these buttons and are defined as two separate static inner classes within the public class of the file . The source code compiles and runs with the main screen being displayed. However when the buttons are clicked they do nothing. Please any suggestions.

Post some code so we can see what it is that you're talking about and maybe help to track down any errors.

Here's the code:

Without looking at your code in too much detail, it looks like you have your references to your frames mixed up.
Try changing your actionPerformed methods. Instead of:
new Feedback();
setVisible(true);
try
new Feedback().setVisible(true);

or put the call to setVisible into the constructors for the inner classes.
