After an upgrade to PD 12 and installation of Parallels Toolbar, my Windows 7 VM will not open the Chrome or IE browsers. Clicking the shortcut just causes an hourglass cursor to appear for a few seconds, then disappear but no browser opens. Network connections and internet connectivity show as active and no problems. Windows Update and Norton Security Online can access the internet from their native icons. It's just that I can't get the browsers to respond. Both worked with the previous version of Parallels Desktop.
