Answer 1

I found that clearing the richTextBox didn't always remove all of the text from the richTextBox using richTextBox.Text = ""; or richTextBox.Clear(); Only the first few lines were cleared.

To fix this issue, I included the Update() function call solved this issue.

richTextBox.Clear();

followed by

richTextBox.Update();

to reliably clear the richTextBox.
