I have two problem with Right-To-Left Text Direction in Word2016:
First: every time I open Word2016 the Left-To-Right Text Direction is on and It is very annoying for me because I usually write Persian language.
Second: Ok after I set it "Left-To-Right" and I write in word and it works well at start. But it happens a lot during typing, When I press some Buttons in order to type in Persian language or I am changing language It change to "Right-To-Left" again and I should change it again and. this happens a lot of times. I don't know when it exactly happens But I checked When I use Ctrl+Shift Buttons it change.(Maybe It happens other times too,I am not sure)
I use Windows 8.1
Edit: for the second problem I switched "keyboard Layout" in control panel to "Not Assigned" But still have the same problem in word when I press "Ctrl+Shift"
