@LarsGit223 .. I would, but of course now it works .... for the first time. The only thing I did different was create a new file and search for some string in it. From then on it worked with any string. But also in other instances, which it did not before. Very weird. I know that the commands were identical.
I took a look at the source code, but that style of coding is not my kind of sports, so no clue what's actually going on.
