    Re: SWT ListBox with SWT TimedMessageBox problem

    Have you tried the example code provided when you asked this question the first time? ( http://discussion.forum.nokia.com/fo...d.php?t=191919) Is that working for you? If it does then it is probable that something inside DescriptionShell code is the real cause.

    If the example code is not working for you then please post the software version of your N97
