Since getting a MBA with Mavericks, my Office 2011, specifically Excel has been very unreliable. I use this for work and I have tow monitors. Whenever I try to switch between an excel page on one screen and another on the other screen, I get the pinwheel of death and it can sometimes be there for up to 5 mins. It is really hurting my ability to do my job on my Mac. I know they are coming out with and Office 2014 for Mac but I need something that works now and I really don't want to have to switch back to Windows. Has anyone else had this issue or have any suggestions on how I might fix it? Thanks in advance!
