Problem with ShowCodeAssist for getting help for a command

2017-11-28 11:38:59

I am running Mathematica 11.2 on Windows.

Since some days I have the following problem: when I move the mouse curser over a command no pop up help is shown.

I found the following related question: in my case ShowCodeAssist is aeready set to True.

I also reinstalled Mathematica, without success.

What could be the problem?
