In a .NET 2.0 web project, I have a property declared as below... The problem
is at design time. When I try to launch the ImageUrlEditor by pressing the
elipse in the property editor... nothing is launched... No error is displayed

Any ideas would be helpful.

[
Bindable(true),
Category("Appearance"),
DefaultValue(""), Editor(typeof(System.Web.UI.Design.ImageUrlEditor),typeof(System.Drawing.Design.UITypeEditor))
]           
public string ImageUrl
{
      get
      {
            string s = (string)ViewState["ImageUrl"];
            return ((s == null) ? String.Empty : s);
       }
       set { ViewState["ImageUrl"] = value; }
}
