A discussion group member reported that he downloaded Autodesk DWF Writer. He installed it on a Windows XP SP2 computer. Anytime he exited Internet Explorer, he got 2 crash reports. If he turned off the Autodesk DWF toolbar, the crashes went away.
Software Engineer, Brian Enright, reported that the problem was due to a defect in the Google IE add-in. Google has fixed the problem, and they have a hot fix.
The DWF Writer IE add-in was not the only add-in that was affected by the Google defect, but it certainly is one of them.
