Hello, and thank you all for your answers.

Unfortunately ..
The problem still occurs in 7.2 with some books (that are not DRM Protected - of course)
I still can't see what makes the Calibre worker process never ends its checking.
If I right-click on the task bar ( Windows 10) over the Calibre editor (bluebook) and choose Calibre worker process, I can see flashing a black windows with sometimes a content.. but it disappears too fast to allow reading its content.

After some tries I could get the flashing content of this black "calibre worker process" window.
Here it is.

Traceback (more recent calls last):
File "runpy.py", line 198, in _run_module_as_main
File "runpy.py", line 88, in _run_code
File "site.py", line 95, in <module>
File "site.py", line 50, in run_entry_point
File "calibre\utils\ipc\worker.py", line 202, in main
File "os.py", line 679, in __getitem__
KeyError : 'CALIBRE_WORKER_FD'
