Keyboard letters give different outputs

Interesting, I will take a look at this, im pretty sure this person is not using firefox however.
Perhaps it has something to do with excel, will need to play around and see if i can get it to replicate.

One detail I'm unsure of is whether the problem was happening when inputting into Word doc's, as only remember it when typing into online content.
The one certain thing though is that an action into an Excel doc 'cured' the problem temporarily.
Just glad that whatever was causing it now seems to have resolved itself.

What i can say is both computers were running windows 11, seemed to be giving the issue when writing emails too (mozilla thunderbird) I wont get a chance to look at it into the new year.
But I suspect it could be some sort of software bug.
