Here's an oddity I've found re. spell-checking whilst editing - I thought I'd post a heads-up.
I've been using the Firefox browser (in Windows) for a while (currently version 91) and have recently noticed (or rather not noticed) that a lot of typos are not being flagged by the browser. So quite a few DW articles have been going out with (my) spelling errors.
The system works fine in Firefox for other sites however - such as this one . . .
I've subsequently found, by testing, that in older browsers - e.g. SeaMonkey and PaleMoon - all the spellchecking still works fine in DW. So I'm going back to using them instead.
I wondered if anyone else has this problem?
