Progressbar behaves strangely

Question

I just created a C # application that uses a thread that polls the UART for a receive event. If the data is received, the event is fired in my main thread (GUI), and the progress bar is controlled using the PerformStep () method (of course, I previously set the Max value accordingly). A call to PerformStep is called using the following expression to handle cross-threading.

this.Invoke((Action)delegate{progressBar2.PerformStep();})

When you run this application, the progress bar never reaches its final value. He stops at 80%. When debugging and stopping in the above line, everything works fine using separate steps. I have no idea what's going on!

Start reading the stream in the main stream:

pThreadWrite = new Thread(new ThreadStart(ReadThread));
pThreadWrite.Start();

Read the topic:

private void ReadThread()
{
while(1)
{
    if (ReceiveEvent)
    {       
    FlashProgressBar();
    }
}
}

An event that fires in the main thread:

private void FlashProgressBar()
{
this.Invoke((Action)delegate { progressBar2.PerformStep();});
}
