Any Netbeans User To Help Me Out Of This Hook.

These are some of the problems i have with netbeans. I'm new to it.
1. I created a JFrame that has a menu. A menu item is used to display another JFrame (say JFrame2). When i close the JFrame2, The first JFrame closes Automatically. How do i make them independent.


2. I want to set a tab order. I used a JTextArea Component. if I press tab after filling some information into the JTextArea, it moves some spaces still in the same JTextArea and does not move the cursor to the next Component.


3. Another problem i have is that, i want to use code to add component such as a JTable to a JFrame created by netbeans, and since netbeans automatically creates the code in the init() method of the form i am confused. I have tried all sort of codes using add(); method in the constructor and it is not being fruitful. Pls help me out.

Thanks
