    Default Problem with the refresh of Swing components

    Hi everyone,

    I have a Swing application which has several Swing components (including a button) on a window.
    When clicking the button, a background DOS command will be executed which takes a long time.
    During this period, if I resize the window, the whole window will be displayed black - no component
    will be refreshed. (Once the background command is complete, the window will be displayed properly.)

    Anyone has experienced the similar problem?
    Thanks for your help.

    - Sean

    Yeah. Stop executing long-running tasks on the EDT. Use a SwingWorker or simply a new Thread instead.
