I don't have a fix but it did fix itself after a few reboots and I don't recall but I may have logged out and back in.
After installing the update, several program icons in the task bar disappeared. The function is still there "under" the blank spot, but there is not visible icon. The task bar has blank spots for the missing icons, but the program can only be identified by holding the cursor over each blank spot. How do I get the icons back?
