Some follow up info.
Here is my code:
txtMessage.EditorOnPaste = CuteEditor.PasteBehavior.PasteText;
txtMessage.ShowBottomBar = false;
txtMessage.AutoConfigure = CuteEditor.AutoConfigure.Minimal;
txtMessage.BackColor = Color.FromA#d1dcff;
txtMessage.ForeColor = Color.FromA#d1dcff;
txtMessage.AllowPasteHtml = false;
txtMessage.FilesPath = "../../CuteSoft_Client/CuteEditor";
txtMessage.BorderColor = Color.Transparent;
txtMessage.BorderStyle = BorderStyle.None;
But you can see what I'm seeing when I paste, why am I getting this pop up on FireFox. Is there a way to disable this pop up window. I don't get it in IE, it just paste the text into the box after I click yes to allow pasting.
