Simple: Move the "huge task" to a BackgroundWorker, and use the progress report to update the RichTextBox.
That way, the UI thread is free to do anything it needs to, including respond to the user mouse clicks!

If programmer call the ReportProgress(Int32) function very much, for example: 1000 per 1 second, the Windows Form dont responed.

Then don't call it so often! :laugh:
Buffer up display updates and issue them all together.
