Hello
With last Calibre Version 7.1 , editor
I had some "unlasting running check"
It displays "Running Check, please wait..".. so I waited hours, and it never found an exit
The Only way to get out was to stop the Calibre working process from the windows tasks management.
It happened with some books I received
( not with books I made and converted to epub. With those ones, the check ran perfectly)
How to know what makes the check "unlast" ?
Thanks so much
