OpenGL context error

dan2the6th · 06-23-2020, 04:04 PM

I've been using the editor to fix a few typos in a large book. Now when I try to open the book for editing again, I get an error box, something about "Failed to create OpenGL context". As usual, it accuses me of not having the latest graphics drivers installed, but I know that isn't correct. I've attached a snip of the error window. Any help, I hope?

What OS are you using?

Sorry, Windows 10 v2004, 64-bit. With 64-bit calibre.

I just tried rebooting my laptop, and the editor started working normally again, at least for now. Maybe just a temporary glitch.

Hi,
I have recently started getting the same error, it's happening frequently. As with original post, I have rebooted, I have the latest drivers installed, Win 10 2004 and I have put the ANGLE ddl files in the program directory but still it happens.
Any assistance/advice appreciated, thanks.

I want to chime in that I get that error too but only when I open 4+ epubs. First 3 epubs open fine. On the fourth and on, it will take 30 seconds to open and then that error comes up. I'm on windows 7.
