Menus don't work properly since I updated today

Hey! Is anyone having an issue with the menus not opening when you click on them? For me, I have to click a couple of times and the hold it so the menu drops down, and then I still can't access any of the sub-menus. I'm also not getting all the options when I right-click on items, and those sub-menus won't open either. What's going on? Anyone have a fix for it? It's really dragging down my workflow. 

Thanks!
