Validate() works very slowly with jse 1.4.2.

Question

Hi, I have a question about the method validate(). I really appreciate it if somebody could help me out.
I have some components (buttons, textfields etc) in a panel. Let me refer it as Panel A. When I click one of the buttons in Panel A, I would like to remove some components and add some other components in Panel A. If I click the same button again, I would like to have Panel A return to the original configuration.
I call method validate() only once after I remove and add components for each click event. This works perfectly with Java 2 runtime environment SE 1.2 and it take very little time. However, this program works very slowly with Java 2 runtime environment SE 1.4. That means with JSE 1.4, after I click the button, the Java applet will still be able to add and remove components, but it take very long time.
Would somebody please give me a hand on this? Thanks a lot!

Thanks for mzarra's suggestion. Here is my code:
// Buttons: virtualModelButton
// Panesls: pp_right, pp_right_bottom, pp_button1, pp_right_top2
else if (evt.target == virtualModelButton)                    
if (virtualModelButton.getLabel() == "Show Virtual Model")
pp_right.remove(pp_right_top);
pp_right.add("North", pp_right_top2);
pp_right_bottom.remove(pp_button1);     
pp_right.validate();
virtualModelButton.setLabel("Show Control Panel");
else if (virtualModelButton.getLabel() == "Show Control Panel")
pp_right.remove(pp_right_top2);
pp_right.add("North", pp_right_top);
pp_right_bottom.add(pp_button1, 0);
pp_right.validate();
virtualModelButton.setLabel("Show Virtual Model");
}
