Problem with colors of button.

[P Jain]

Hi!
I am facing a poblem with color of button. I have colored the buttons in a panel,when I presses any button its color gets changed from it previous color.
In my application I have a Text Field and a button in a panel,when I presses that button the title of button should be print in the text field,but when I presses the button the text gets printed in the text field but the color of the button gets changed and a dim image of printed text(in text field) appears on the button.
How can I solve this problem.
