I am getting the Thunderbird pop up that are needed to do things in a very small window that is not able to resize. And hence not able in some cases to close out the window. Thus on this particular incident, I cannot close the message I want to close out. I don't need it so I would just discard it. This pop up would say something to the effect do you want to cancel this message? But as you can see there are no button. I cannot close out the screen as I need to press a button but it is not available. This is Version 102.3.3. I am also getting Bogus messages from time to time telling me I need to manually upgrade Thunderbird but when I download it is 102.3.3. What happened to auto update? So to close out this window, I go to Sysinternals Process Explorer and find the remaining Mozilla program and kill the remaining Thunderbird. The main Thunderbird I am able to close. But this new message remains due to this pop up artifact.
