BackgroundWorker and WebBrowser Control
<p>Is it possible/recommended to use background worker threads with the web browser control?</p>

<p>I am creating a bot that searches google for keywords, then checks for sites in the first 10 pages to see if a site is ranked.</p>

<p>The user can provide a maximum of 20 sites to check, and can use proxies. So ideally I'd like to have 5 threads working at once.</p>

<p>Is it possible? I might have heard somewhere that there are problems with WebBrowser control and threads.</p>
