AJAX :: Can't Make Editor's Height Smaller Than 200px

Ive downloaded AspNetAjaxLibraryBeta0911 and have added both System.Web.Ajax.dll and AjaxControlToolkit.dll from the webforms/debug folder to my [ASP.NET web app] project. I have also added the latter dll to my toolbox. Ive dragged a ToolkitScriptManager onto my aspx page too, and it has created these two reference:

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>
<%@ Register Assembly="System.Web.Ajax" Namespace="System.Web.UI" TagPrefix="asp" %>

Is that right so far? Now I want to have a custom HTMLEditor, so I created a new folder "App_Code" and created a class calles CustomEditor.cs which has this content:

using AjaxControlToolkit.HTMLEditor;
namespace TestProj.App_Code
{
public class CustomEditor : Editor
{
protected override void FillTopToolbar()
{
TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.Bold());
TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.Italic());
TopToolbar.Buttons.Add(new AjaxControlToolkit.HTMLEditor.ToolbarButton.Underline());
}
}

and then I added this to the aspx page:

<%@ Register namespace="TestProj.App_Code" tagprefix="custom" %>
and
<custom:CustomEditor ID="editorMsg" runat="server" />

Firstly, it works. But I have a few problems.

1) In CustomEditor.cs there is no intellisense, and pressing Ctrl + Space bring up no things like "TopToolbar" etc.

2) In the aspx page's designer code I had to add this manually: protected global::AjaxControlToolkit.HTMLEditor.Editor editorMsg; else it wouldnt come up in my code behind. Why isnt it automatically doing that? And is that correct?

3) No matter what I do I cannot make the editor's height smaller than 200px. I set it both inline and in code behind but it still overflows its container and goes to 200. I can however make it more than 200 and also width is fine. Heres a screenshot: [URL]
