Found a solution:

In the registry there is the key

HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\C ommon\LanguageResources\EnabledLanguages

with several entries like "1031" etc., which represent specific languages. You can choose them in Word at the bottom left of the program.

One entry (1031, German) was set to "On", which is ok. The other entries were set to "ExplicitOn". I changed all of them to "ExplicitOff" and my problem was solved. I can click on the right side of text and the text cursor gets positioned there at the end of the line. Wonderful.

Only thing was, that the earlier mentioned language selection "button" was gone. So I changed one of the entries (1033, EN-US) back to "ExplicitOn". This brought back the language menu.


I think Word got confused somehow with Arabic language. I experimented with it some days before because of technical issues in the following work process. This might have caused my problem.
