    Question The control panel strip of MediaPlayer is blank when content is playing

    Description: Sometimes the control panel strip of MediaPlayer is blank when content is playing. All the buttons on the panel are then invisible.

    OS: Microsoft Windows XP [Version 5.1.2600]

    Java: java version "1.5.0_06", Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05), Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed

    mode, sharing)

    JMF: jmf-2_1_1e-windows

    Web browser: IE 6.0.2900.2180.xpsp_sp2_gdr.050301-1519 or Firefox 1.0.7

    Source code: MediaPlayerSample.java under the "JMF_samples" directory

    Reproduce:
    1. Run MediaPlayerSample.java as an Applet with any .wav audio file or .avi video file
    2. Click the "refresh" button of your browser (I use IE or Firefox) until the control panel strip turns to blank.
    In general, it appears within 20 clicks of "refresh" button.

    Knute Johnson in comp.lang.java.programmer told me to update JDK to 1.6.0beta2 and I found this problem disappear in 1.6.0beta2.
