Intermittently on my network, certain machines will be unable to open a link that opens in a new browser window. If I turn the proxy settings off, the browser responds properly. When the proxy settings are re-enabled the new browser window fails to open again. It just hangs as an open empty white screen. I can manually open a new browser window, it will work just fine. It only occurs on when a link attempts to open a new window. Also it isn't consistent throughout the network only on select machines, both Windows XP with IE 6 and W2K Pro with IE 6. Any thoughts.
