Hi all!
I really need to show neat and professional looking messages, like helper tips, or error notifications, in quick succession, often occurring before the first message has disappeared....

I was trying to display those notifications in a ToolStripStatusLabel, but whats happening with my code is I have to wait for my background worker to finish displaying one message, before the other can be displayed and this hangs the UI thread, completely crashing the program.

//This method allows users to display auto-disappearing messages using a BackGroundWorker (bgwStatus) and a ToolStripStatusLabel (tssLabel1)

private void showNotification(string message, Color color, int barValue)
{
	tssLabel1.ForeColor = color;
	tssLabel1.Text = message;
	tsPBar1.Value = barValue;
	if (bgwStatus.IsBusy)
		bgwStatus.CancelAsync();
	while (bgwStatus.IsBusy)
		Thread.Sleep(20);
	bgwStatus.RunWorkerAsync();
//Thread waitForNotification = new Thread(waitForNotificationOpportunity);
//waitForNotification.Start();
}

//In this Method the BackGround Worker Waits for about 2 seconds

private void bgwStatus_DoWork(object sender, DoWorkEventArgs e)
{
	for (int i = 0; i < 40; i++)
	{
		if (e.Cancel || bgwStatus.CancellationPending)
			return;
		Thread.Sleep(50);
	}
}

//Once the Time period (2 secs) has elapsed, the Label and the progress bar are reset.

private void bgwStatus_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
	tssLabel1.Text = "";
	tsPBar1.Value = 0;
}

I'd really appreciate the help. Thanks!!
