I have some text in richTextBox1. 

1. I have to sort the words by their frequency and display them in `richTextBox2`. It seems to work.
2. Have to find all mistaken words and display them in `richTextBox4`. I'm using Hunspell.
Apparently I'm missing something. Almost all words are displayed in `richTextBox4` not only the wrong ones.

Code:

```
foreach (Match match in wordPattern.Matches(str))
{
    if (!words.ContainsKey(match.Value))
        words.Add(match.Value, 1);
    else
        words[match.Value]++;
}

string[] words2 = new string[words.Keys.Count];
words.Keys.CopyTo(words2, 0);

int[] freqs = new int[words.Values.Count];
words.Values.CopyTo(freqs, 0);

Array.Sort(freqs, words2);
Array.Reverse(freqs);
Array.Reverse(words2);

Dictionary<string, int> dictByFreq = new Dictionary<string, int>();

for (int i = 0; i < freqs.Length; i++)
{
    dictByFreq.Add(words2[i], freqs[i]);
}

Hunspell hunspell = new Hunspell("en_US.aff", "en_US.dic");

StringBuilder resultSb = new StringBuilder(dictByFreq.Count); 

foreach (KeyValuePair<string, int> entry in dictByFreq)
{
    resultSb.AppendLine(string.Format("{0} [{1}]", entry.Key, entry.Value));
    richTextBox2.Text = resultSb.ToString();

    bool correct = hunspell.Spell(entry.Key);

    if (correct == false)                
    {
        richTextBox4.Text = resultSb.ToString();
    }    
}

```
