I just wanted to see if this is a general problem with the current versions of Microsoft Office for Mac 2016. I have a 15" rMBP. When I use it as a laptop it runs on the iGPU. When I get home I dock it to a few monitors and other peripherals and it switches to the dGPU. Word and Excel are randomly crashing each time the GPU switches. I'd say about 70% of the time. Have any other users experienced this? I have to say that Office:2016 is a huge disappointment. I was okay with Office:2011 and it rarely crashed on me. Office:2016 has been lagging and crashing so much that I've started just using the Windows version through VMWare.
