Hello,
I've had this problem twice in 2 days. The editor no longer works. It freezes. I have to close it by force. I am able to solve the problem using the method given by Kovid for the same problem in this post:

But after 2 days, the problem reappears.
The viewer works correctly, as does everything else. It's rather annoying to have to set up the editor each time.
The first time I had this problem, I hadn't yet updated to the latest version of calibre, 6.25.
Once the update was done, the problem remained.
And now it's reappearing again.
What could be causing this problem?

Thanks!
