I have some kind of Programming Lab (11.0.1 on Win10) - Notebook, which does exhaustiv calculations (FindClusters from 14 millions of data in my case). It should finish after 20 or 30 minutes or the like.
But indeed, it does never finish, not even after days, if other processes are running on my PC: Edge, IE, Firefox, Excel, Word, or the like. The WL-Desktop just seems to do nothing after some time. Which can be observed within taskmanager. If I start the notebook from a freshly started Win10 with nothing else running, it terminates within reasonable time as expected.
Quite weired. How can a Wolfram-Language-application influence the operation systems task management?
