There seems to be an automatic language detection effort behind the spell checker. It performs badly and it seems to be not possible to override it; the setting through File > Language is not necessarily respected. It is all very erratic. Sometimes someone will report here a dozen English words that aren't recognized, and someone else will try to reproduce it and for the other person some of the ordinary words are recognized and others not.
I have conjectured that sometimes the automatic language detection algorithm decides that the language is Basic English [1]. I believe that that would explain the system not accepting contractions such as couldn't and didn't, and it would explain the error message for quite a lot of ordinary words. However, we have also seen a report that "simple" wasn't recognized [2], and it is a Basic English word.
If the spell checker refuses to recognize any word typed then that is easier to explain; it has gotten itself into a state where it is checking for a different language. In the "simple" example earlier it seemed that the spell checker still was set on something like English. |
