When I am typing in an email, it will type a few words, then, freezes for 3 ~ 4 seconds, or so, then, with catchup to where I was typing. If I have a mistake, and use the arrow key to move the cursor, it will move a few spaces, then freezes. I have to stop, wait for the cursor to appear again, then hit the arrow key again, and repeats. Moves a few letters/spaces, and cursor disappears again. and I have to wait again a few seconds to get the cursor back. I end up, just having to use the mouse to click where I need to go, so I can correct the spelling. ... some time ago, I ran across some pc -hack?- where you delete ALL temp files, and a couple of other things, that I dont remember now, which I did, and Thunderbird works fine - for a little while, as in few minutes I think it was, then was right back to hanging up/freezing - for several seconds. Has gotten so, I have had to go back to Outlook most of the time. Or maybe Onmail. ... Using Win 10 Pro Version 22H2 Build: 19045.3930 If this means anything to you.. ...
