Hi there,
I use the Dark Gray theme for Office 2016 and recently when no document is open in Word, rather than seeing the normal dark gray background like this
I'm instead seeing a white background in the document area.
If I change the theme to another and then back to Dark Gray, I get the normal dark gray background again. but next time when I close a document, I get the white background. I've run the Office 2016 Online repair and this doesn't fix it.
Any suggestions?
