Well many thanks for you in the first place I would say.
And indeed I'm very happy that we found the cause of the problem. It was stupid of me to forget that my Jmix was still in the "Rottmeier modification".
But it had been ages ago that I had used the Jmix and forgotten to do alt+shft+ctrl+T. And then it stays in the program, doesn't it?
Now I know for sure that these kind of exercise will work in Moodle I intend to make a whole series of it ( at least 20 exercises. Everybody who teaches ESL can use it.
