.net - How do I open a FolderBrowserDialog at the selected folder?

Question

I have a FolderBrowserDialog, displayed with code shown below. However, it keeps opening with 'Computer', i.e. the root of the folder tree, selected. How do I get it to open on the selected folder?

       var folderBrowser = new FolderBrowserDialog();
        folderBrowser.Description = "Select Chase 6 Installation Folder";
        folderBrowser.RootFolder = Environment.SpecialFolder.MyComputer;
        folderBrowser.ShowNewFolderButton = false;
        if (Directory.Exists(Properties.Settings.Default.defaultChasePath))
        {
            string x = Properties.Settings.Default.defaultChasePath;
            folderBrowser.SelectedPath = x;
        }
        if (folderBrowser.ShowDialog(this) == DialogResult.OK)
        {
            chasePathtext.Text = folderBrowser.SelectedPath;
        }

If you set RootFolder to Environment.SpecialFolder.Desktop then it will open to the SelectedFolder as long as the path is valid.

When you set RootFolder to Environment.SpecialFolder.MyComputer, then the first time the dialog opens, it will always start at MyComputer, not the SelectedFolder path.

If a valid selection is made, then subsequent uses of the same FolderBrowserDialog instance will open at the previously selected path.
