Restore basic functionality
I work on a Mac running El Capitan. When establishing or changing any meeting with WEBEX the program freezes. Forcing the program closed does not solve the problem. Rebooting the machine does work. Our contracted computer support says, "This is a known issue. Check back in a few weeks and maybe Microsoft will fix it". Its been a week.
I loved working on a Mac. Using Microsoft software is making this experience just as poor as working on a Windows Machine.
