Problem with Thread::isRunning()

[Mathias Biere]

Hi,
I'm new to CommonC++ and have problems using the Thread class.

In the following piece of code Thread::isRunning() does not return false
if the thread leaves its Run() method. I guess this is the purpose of 
isRunning()? (The main program continues printing "#" every second after the 
thread has printed "Final()"... )
I am using CommonC++ 1.4.3 on Linux 2.4.4 and Windows.

###########################################
class MyThread: public Thread
{
        virtual void Run();
        virtual void Final();
};

void MyThread::Run()
{
        for(int i=0;i<5;i++)
        {
            Sleep(1000);
            cout<<"."<<endl;
            }
        cout<<"Thread finishes"<<endl;
}

void MyThread::Final()
{
    cout<<"Final()"<<endl;
}

int main()
{
        MyThread* mt=new MyThread;
        mt->Start();
            while(mt->isRunning())
            {
            cout<<"#"<<endl;
                sleep(1);
            }
        cout<<"Finished"<<endl;
        delete mt;
}

Many thanks if anyone can tell me what's wrong.
