How do you animate a rectangle upon hovering over a PNG using mouseover(file dl)?

Question

I have two sets of PNG images, one is text and the other is the text mask. I have a rectangle on top of the text and under the text mask. I want the rectangle to  glide over the text upon hovering over the text PNG and stop. I have accomplished moving the rectangle, but for some reason when I try to implement mouse-over, the rectangle just plays upon loading, and doesn't react when I move my mouse over it.
I've tried almost all approaches I know, but none have worked.
Thank you for your help.

You are using netbeans to build your jar. Go to your project properties (right click on the project name and choose properties). Then select "Run" from the tree. You will find a text box "Main Class" there, put the name of the class in there that has your main() method, including full package if you have one. That is WITHOUT the .class extension.
Build your jar, it will be placed in the dist directory of your netbeans project. You can now run it from netbeans itself if you want. If ever you want to run the jar from the command line on your home machine, just navigate to the directory with the jar file and execute this:
java -jar yourjar.jarand you're off. If your runtime environment is propertly setup you can even execute the jar by simply double clicking on it from the windows explorer. No need to change the CLASSPATH variable at all, in fact it is ignored when executing a jarred application.
Also a note: you do not need to reboot your machine when you change an environment property. Simply change them using my computer -> properties -> advanced tab -> environmental variables. If you have any command prompts open, close and reopen them so the properties are updated properly.
