I am working on a wpf application. Here I need to use System.Windows.Forms.FolderBrowserDialog in my Wpf application.

        System.Windows.Forms.FolderBrowserDialog openFolderBrowser = new System.Windows.Forms.FolderBrowserDialog();

        openFolderBrowser.Description = "Select Resource Path:";
        openFolderBrowser.RootFolder = Environment.SpecialFolder.MyComputer;
        if (openFolderBrowser.ShowDialog() == System.Windows.Forms.DialogResult.OK)
        {
            //some logic
        }

when I select a Folder and click OK, I launch another System.Windows.Forms.FolderBrowserDialog with same code, My problem is when I select a Folder and click OK, the shadow of FolderBrowserDialog remains on the screen(means my screen doesn't refresh). I need to minimize or resize it in order to remove the shadow of FolderBrowserDialog. How can I solvet his issue? Any help plz?
