Switching Screens Speed?

Question

Hello everyone again,
I'm pretty new to programming in Java and I'm getting an error in my program. The program runs fine but it's slower than I wanted. The Windows Consol does not give any errors. The program displays a title screen of a game I'm making with background music and a button. When the button is pressed, it changes screen to a 2nd screen which also has a button. The 2nd screen playes a different music and also has a button which exits when pressed. Pushing the Esc key exits out of the game, which is full screen. However, there seems to be a delay of 5 to 20 seconds every time I push the button to switch screens and whenever I start the program. Why is it doing this?
I have some ideas, but I'm not sure if they are right. I'm guessing that it really slows down because I need to buffer the images. If it's not the image that slows down the program, is it the SoundManager? Maybe it's something I'm not seeing, so please take a look and give out any suggestions.
Thanks
Here's the code...

Answer 1

I do agree... it could be the sound manager, cause if i am not wrong once the song/sound is loaded.. it is not garbarge collected when the new sound is loaded. Maybe you might want to ensure to get rid of the previous sound before loading the next one???
