when I try to click on the designer tab to get the designer view, I get this error:

I'd like to get into the designer and have no idea what's wrong. My Form1 code looks like this at the top:

```
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Drawing.Drawing2D;
using System.Diagnostics;

    namespace foobar
    {
        public partial class Form1 : Form
        {

        List<CharLabel> allChars = new List<CharLabel>();

        public Form1()
        {
... etc ...

```

Any ideas?
