I'm marking this as _critical_ because app hanging is similar to a crash (as it leads to data loss). I've waited 5minutes already and the UI doesn't recover from a "Not responding" state, so I've had to kill the app and lose all the work that I had been doing from the last time I saved the document. This has happened to me on Windows (v7.5.4.2), but it may happen as well in other platforms. I cannot reproduce this bug, though, for very small document (around 2 pages), but I can reproduce it reliably for a document of around 100 pages. Steps to reproduce: 1. Open large document (in my testing, the language I can see in the status bar is "English (Hong Kong)"). 2. Tools -> Language -> For All Text -> Spanish (Spain) Expected results: Change language in status bar, and maybe start highlighting in underline-red the words that are no in the Spanish dictionary? Current results: It hangs, I cannot use LibreOffice for 5minutes already and so I need to kill it. (Maybe with a large document, this action may take time, but if this is the case, the way to fix it is showing a progress bar to the user so that she doesn't suspect that the app is dead.)

Thank you for the report, Andres! Can you please test the pre-release for 7.5.5, as I am pretty sure you are encountering bug 155939, which is already fixed: https://www.libreoffice.org/download/download-libreoffice/?type=deb-x86_64&version=7.5.5&lang=en-US I am pre-emptively marking as a duplicate, but please report back on your test and mark as "unconfirmed" if it turns out I am mistaken. Thank you! *** This bug has been marked as a duplicate of bug 155939 ***
