All of a sudden I am unable to open Google Chrome as my browser? Suggestions please?
Have you tried using Chrome under a different user account (you might need to create one, of course)?
Either way the first thing to try would be to uninstall it and re-install it...assuming you have not tried that already. If the new user account did help, them it might be corrupted preference files...if so, then uninstalling and re-installing would likely fix that.
