I have updated my computer. Now ALK runs with 50% load while not doing anything (the Task-Manager states 50%, while ALK measures itself with 1%).
Whatever I do, there’s nothing updated on the screen (removing a track, starting playing) within a reasonable amount of time. I tested by deleting a track, and it finally disappeared after 51 seconds, possibly that I counted to slow and it takes a timeout of 60 seconds.
It looks like the core-ALK is still running, while the display is running wild.
I have already removed the current configuration and restarted it again, but it is still the same. There are no dump-files.
