Internet Explorer was recently opened and the 'Favorites' button clicked.
IE immediately started opening multiple tabs in rapid fire succession.
Within seconds IE had thirty or so tabs trying to open with more coming at great speed.
With IE not responding to attempts to stop, cancel or to close,
the cursor was put over the 'Start' button with intent to shut down the system, but even before it was clicked Win7 went into shut down.
After several reboots and several more of these crazy session things seem to have settled for the time being.
What should I look for?
Is this a known problem?
Is there a fix?
