有时，当我取消BackgroundWorker时，整个GUI都崩溃了.

Sometimes when I''m Cancelling my BackgroundWorker, the whole GUI collapses. Any ideas why it could happen?

handler.WorkerReportsProgress = true;

和

and

BackgroundWorker worker = (BackgroundWorker) sender;
while(!worker.CancellationPending)

    // Dequeue from queue... and do some stuff
