Other questions

Does the issue still occur after restarting your PC?


Have you tried any other versions of NVDA?

Yes it is a regression. This is working correctly in NVDA 2018.1 and failing in NVDA 2018.2 and above
cc @michaelDCurran @feerrenrut This is pretty serious for those using Excel 2010, because it fails similarly in many more edit fields. Can this be assigned P2 ad least and fixed asap?

Try to use window.edit.Edit when an editable window supports it (#8165)

* Try to use NVDAObjects.window.edit.Edit when an editable window supports it regardless of window class. Also, try ITextDocument in more cases and remove old pre Windows Vista code

Inherrit from RichEdit

* Fixed one case where the movement of EM_CHARFROMPOS to winUser wasn't reflected

@leonardder can you please look into this? It makes more advanced operations in Excel 2010 pretty frustrating to achieve.

It fails also in Excel 2019. Can this be looked into?

I'm sorry I haven't looked into this sooner.
Looks like this also bugs in Narrator, so there's definitely something horribly wrong at the Excel side of things. I will look at your pr.
