An opened eMail jumps or hides itself
When opening an eMail, all of it cannot be seen. Here are the steps to create or see the problem.
Steps to show the Thunderbird v78.11.0 Problem Our Computer Configuration Windows 7 Professional Thunderbird v78.11.0 Options under Reading & Display are set to Open messages in: “A new message window”
- Open Thunderbird
- Double-Click an eMail in the Inbox to open it. The eMail opens in a new window. When it opens, it's window is horizontally about ½ of the width of the monitor screen, and vertically that window's top edge is at the top of the monitor screen, and that window's bottom edge extends below the bottom of the monitor screen.
- Click on the Top Edge of the eMail's window to drag the window's top edge downward, to make the height of the window shorter. As soon as you mouse click and start to drag the top edge down, the top of that window jumps below the mouse, towards or to the bottom of the screen.
That is the first step of the problem.

ok, I changes to open in a new window and the windows opened with my mail showing the default height and width. roughly 1 third of the wide screen width and the height of the window less the windows start menu bar.
I drag the windows borders on the left and bottom to set new dimensions, closed the window and opened the mail again and the new size was restored.
Then I double clicked the top of the window title-bar to maximize the window to the screen. This also saved the default to maximized on subsequent messages.
Then I grabbed the top of a non maximized window to place the bottom off the screen and the bottom on the third attempt went off the screen as some sort of auto shrink thing was reducing the window to fall above the start menu.
I closed the window and reopened it and the bottom of the display was again set to above the visible area of the screen, despite the original window having the bottom below the bottom of the screen.
Perhaps this is some sort of display issue creeping into windows 7. You might try changing the hardware acceleration setting in options. (search hardware in options)
On a personal note you might want to look at using a later operating system. My experience on update to windows 10 was software that I had issues with that required special treatment to run in windows 7 ran without anything special in windows 10. So it is not all bad.
