Using Mozilla 0.8, I am unable to exit the Preferences window while saving my changes any time that I try to turn off the Internet Keywords feature. I am able to Cancel rather than Save to exit the dialog. This is the only preference item I've found that results in this problem. Switching to another preference panel in the Prefs dialog does not help. As long as I have tried to turn off Internet Keywords, I am unable to exit and save the prefs. If I edit other preferences but not Internet Keywords, I can exit while saving my changes.
