I use IE. Not sure which version. Maybe 9? From the main screen in world Guinness, when I hover my mouse over the 'world office' button, the drop down menu does not appear. I have to go to another screen, say 'managers office', and then from there when I hover over 'world office' I can get the drop down menu. Its very interesting because I don't have that problem in my other two worlds. Does anybody else have this problem in any of their worlds?
