Warning: Thread.suspend() was called; Navigator deadlock might result

[Randall Twede]

I have a page with some applets on it. In Netscape I get this error when I leave the page.
Warning: Thread.suspend() was called; Navigator deadlock might result
Why? Then when I close the window I get an windows warning that Netscape committed an illegal act.
OK one of the applets starts a thread that scrolls some text. I suspend that thread in stop() not the thread running the applet.
public void stop() {
if (runner.isAlive())
runner.suspend();
}
Netscape does freeze trying to load a different applet from another page about half the time.

Randall,
Thread.suspend() is deprecated... something like this may work better :

public class ThreadApplet extends java.applet.Applet
{
    private Thread runner;
    public void start()
    {
        runner = new Thread();
        runner.start();
    }
    public void stop()
    {
        if( runner.isAlive() )
        {
            runner = null;
        }
    }
}

This code should work fine in the majority of cases... however, if your Thread actually contains info that will be important in the Applet even if it is 'switched off', you will probably need to do something with nested loops...
HTH,

Nathan,
I think that would work ok. It was my first applet and a tutorial showed me to do it that way
I need to change the background color of the applet anyway since Netscape has a default of white(same as the page it is on). It is all jarred up and I am lazy though.
