While trying to save settings in IE it does not saves it Sometimes when you make changes in your Internet Explorer and when you restart the machine next time it resumes old settings and you find that your settings are gone. The solution is very simple, find the .plist file saved in the library and delete it. Now launch IE all over and then try to make changes as soon as the application is launched. This is one of the most annoying act of IE while working on a Mac and I suggest using Safari or the choice of webmasters... Firefox.
