Finally I got a few logs:

Up to here, I slewed to a star, a bit east of the meridian, I think it was Beteigeuze...

Here I had to stop tracking manually, because the "start" button was greyed out.

After that, polar alignment performs great....

I think, that when you change the step size from 30 degree to e.g. 20, then Tracking stops automatically and the start button becomes active, but after the initial slew and without changing the default parameters, the start button keeps being disabled, which is understandable, because how should the software know, that a polar alignment is "wanted"... .
