I'm pretty sure this issue has something to do with my AMD Radeon RX 6800 XT or its drivers. I loaded Calibre onto my wife's Windows 10 computer, highlighted the About Calibre (or whatever it's called) epub that it comes with, hit "T" to edit and ALT-F4 to quit the editor about 50 times. No problem. I even moved over a little test epub I threw together about 6 months ago and tried that. No problem. The biggest difference between her computer and mine is she's got an Nvidia graphics card and I've got an AMD one. Her system looks like this:

If anyone out there has an AMD graphics card, I'd appreciate it if you could highlight any epub (version 2 or 3), and hit "T" to edit it and ALT-F4 to quit the editor repeatedly (maybe a dozen times). Let me know if it's successfull all the time or if it has issues.
