I have 2016 MBP with Touch Bar, Radeon Pro 460, macOS Sierra 10.12.2 installed. Word 2016 is sluggish and keeps reporting that I either won't be able to undo an action or am not able to perform it at all because I do not have enough memory.
I have 16 gigabytes of RAM, Word consumes about 350MB while working on 40-page document. It doesn't matter if I have 1 or 10 gigs free memory, the message appears regardless of that. I have over 800GBs free on my SSD. Is that another bug in Microsoft's product?
