Windows 10, Office 2016 and Office Tab 13.10(64bit)
Several files/tabs are open in MS Word.
Whenever I close the last tab (i.e. the one last opened) , Word disappears. The Word window is gone and there is no Word icon on the Task Bar.
I have to relaunch Word, and it opens as it never was closed, with all the tabs in place. (That why I think it only disappears and not closed down).
