can't scroll thru an email

[ruggb]

I just updated to v52.1.1 and I have not noticed this b4.
I cannot scroll thru ONE particular email. All the others I tried scroll fine, so why just this particular one?
I can open it in MAIL or OUTLOOK (desktop) and it will scroll.
I can upload eml file if I knew how to attach it - or include source in msg.

I don't know. Thunderbird is less tolerant of errors in the MIME layout than many other email clients. It also sometimes makes assumptions that it shouldn't. You might be running into an example of that.
