I can confirm that I was having the same issue as well. I followed the instructions about hiding the global menu, and I have not had any problems as of yet. I could not right-click the indicator applet though, I had to right-click the panel, click on panel, then click on Panel Preferences, then select the Items tab, then select Indicator Applet, and then click on the notepad & pen icon to edit it, and then I could put a check mark next to Application Menus (Global Menus) to hide it. Then I restarted the panel using the command in the terminal. I am running Ubuntu 14.04 Trusty LTS. I hope this helps others as well.
