Text wrapping on preview not always working

Something changed after a recent update in the way text wrapping works on both the email previews (main client) and sometimes on the displays shown on the actual email. I’m willing to accept that something changed on the emails I’m receiving but I haven’t figured out the pattern. The problem I really need addressed is on the main client display. If the problem is with the email that’s actually been sent, the main client shows the text unwrapped and provides a very narrow scroll bar at the bottom that I can’t seem to activate. I would love it if the lines got wrapped if they are too wide for the screen (I would think this could be independent of the original email), but if it can’t I need to be able to scroll to see the rest of the text. Sometimes I’ve got so many things happening on my screen that I don’t want to open the email to be able to read it. I hope I’m making sense. Is anyone else seeing this since the most recent version update?
