My drop down commands suddenly stopped working in the middle of working on a document. I was changing fonts of certain parts of the document by selecting the text and using the right click command. I noticed I could still change it using the tools at the top of the page. Nothing in my right click command works and neither does anything in the drop down tabs at the top like file, edit, layout etc. For example I can't save or print without using the keyboard shortcuts. It allows me to select the action but doesn't do anything. I don't believe I would have accidently hit anything since what I was doing is a pretty simple task. Any suggestions?
