I 'think' you're looking for the menu bar. Click the alt key and it should appear. While it's visible, click view>toolbars>menu bar to keep it visible.

Unfortunately it did not solve the problem. I try to explain again, for perhaps I was not able to describe the problem clear enough....

In my former laptop I could see (in Thunderbird) the contents of the email at the top of the list with mails. I could view that half way the screen, right under the email. I'ld like to have that back again, because without that view I have to click on the new mail in order to read it and then I can decide what to do with it. More clicks, for me unneccesssary.....

How can I bring that view back again in this program? My new laptop has the newest Windows 11 on it, so that might give this problem....?

Okay, try this: click view>layout and try different settings. The pane that shows the email content can be activated by pressing the F8 key in case the message isn't appearing.

YES!!!! David, you are great!!!! It solved the problem! Thanks sooooooo much! Hug from Frea!

Thanks for the hug. :)

Hello David, May I ask a final question about this problem? I see that your suggestion has solved more than half of it. What remains, is that the viewing panel is too wide and I cannot make it smaller, zo that I can see the total left side of my screen on which my accounts are visible. You have - hopefully - a last suggestion to improve this?

Can you do a screenshot of what you're viewing? I use the vertical view with no problems.
