Thunderbird freezes when sending emails — Messages are only sent after minimizing the window (Windows 11)

Leonet

Hello, I'm experiencing a very unusual problem with Mozilla Thunderbird. System information: - Operating system: Windows 11, version 24H2. - Thunderbird: Version 153.5.0 (32-bit), ESR channel. - Email accounts: POP and Hotmail (IMAP). Problem: Thunderbird works perfectly when reading emails, browsing folders, and composing messages. However, whenever I click the Send button, Thunderbird freezes and becomes unresponsive. The strange thing is that as soon as I minimize the Thunderbird window, the email is sent successfully. This happens consistently. Troubleshooting already performed: - Created a completely new Thunderbird profile. The problem persists. - Tested different email accounts (POP and IMAP). Same problem. - Tested Thunderbird in Troubleshoot Mode. - Disabled hardware acceleration. - Tested switching windows using Alt + Tab. - Disabled automatic spell checking. - Confirmed Windows Search indexing is disabled. - Checked that Windows operates normally outside Thunderbird. None of these steps resolved the issue. My original Thunderbird profile contains approximately 17.3 GB of important emails, so I would prefer to avoid deleting or rebuilding it. My question: Has anyone experienced this specific issue where Thunderbird only completes sending an email after minimizing its window? Could this be related to Windows 11 window management, accessibility features, or a Thunderbird bug? I would appreciate any suggestions that do not involve deleting my existing email data. Thank you!

ESPAÑOL — Traducción Asunto: Thunderbird se bloquea al enviar correos: los mensajes solo se envían cuando minimizo la ventana (Windows 11) Descripción: Hola: Estoy experimentando un problema muy extraño con Mozilla Thunderbird. Información del sistema: - Sistema operativo: Windows 11, versión 24H2. - Thunderbird: Versión 153.5.0 (32 bits), canal ESR. - Cuentas de correo: POP y Hotmail (IMAP). Descripción del problema: Thunderbird funciona perfectamente cuando leo correos, navego por las carpetas o redacto mensajes. Sin embargo, cuando pulso el botón Enviar, Thunderbird se bloquea y deja de responder. Lo extraño es que en cuanto minimizo la ventana de Thunderbird, el correo se envía correctamente. Este comportamiento ocurre de forma sistemática. Pruebas que ya he realizado: - Crear un perfil completamente nuevo de Thunderbird. El problema continúa. - Probar diferentes cuentas de correo (POP e IMAP). Ocurre exactamente lo mismo. - Ejecutar Thunderbird en modo de resolución de problemas. - Desactivar la aceleración por hardware. - Probar a cambiar de ventana con Alt + Tab. - Desactivar la corrección ortográfica automática. - Comprobar que la indexación de Windows Search está desactivada. - Verificar que Windows funciona correctamente fuera de Thunderbird. Ninguna de estas pruebas ha solucionado el problema. Mi perfil original de Thunderbird contiene aproximadamente 17,3 GB de correos importantes, por lo que prefiero evitar eliminarlo o reconstruirlo. Mi pregunta: ¿Alguien ha experimentado este problema concreto, en el que Thunderbird solamente consigue enviar los mensajes cuando se minimiza su ventana? ¿Podría estar relacionado con la gestión de ventanas de Windows 11, las funciones de accesibilidad o algún error de Thunderbird? Agradecería cualquier solución que no implique eliminar mis correos existentes. ¡Muchas gracias!

Hola, El perfil totalmente nuevo eran con los 17Gigas de Correo? Probo desactivando temporalmente el Antivirus? Porque usa Thunderbird 32bit en un equipo y sistema que seguramente es 64bits? Saludos
