Windows 10 updated this week, and since then Calibre can no longer open pop up windows, eg. if I try to edit metadata. Then, whatever I try to do, I get the Windows error bing. I have to use Taskmanager to shut Calibre down.
I updated to V7.26, still the same.
The windows update MIGHT be a conincidence but ....
Has anyone else seen this? Any clues?
