@alf.krause,
Try to manually generate a report by EurekaLog for all running threads, this might help, you can call it manually or raise an
exception, with EurekaLog settings set to pause all threads when generating a report.
Your screenshot showing a thread not the main thread and most likely that is
OS one not even created by your application, open Threads while debugging with
IDE.
Here a screenshot showing on the right what do you see (
OS threads aka externals) and on the right the main thread, in your case there might be more, either yours or
OS's:
Also you want to see if some
API is in fact had executed and returned or not, so i suggest
API monitor, there was a post explaining how to use it, and here what you might need to select
Hope that helps.
