I have now found how to suppress the caret by 'importing' Win32 as follows:

/// <summary>
/// The HideCaret function removes the caret from the screen.
/// </summary>
[DllImport("user32.dll")]
private static extern bool HideCaret(IntPtr hWnd);

and then invoke it as follows:

HideCaret(mainRichTextBox.Handle);

for:

private System.Windows.Forms.RichTextBox mainRichTextBox;

Only problem is that the caret re-appears when the mouse is clicked anywhere in the client area! Hopefully, I will find a way round this one too.

Thanks once again,

Paul
