It seems to have fixed itself now, but I was just posting on a thread, and whatever I typed in the reply box, I could not get a letter K to appear. I would have thought it was my keyboard, as I'm posting from a Windows PC on the desktop site on Chrome, but it worked fine in another window, and as you can see, it works normally now.
I wouldn't have thought anything of it, but I noticed a few days ago another poster had the same issue. It's not consistent as I can see most posts do not have this problem, but I thought I would put up a thread, in case people experience a similar thing.
My only thought is could it possibly be that the letter "K" is assigned as some kind of shortcut and it's meaning that it's being ignored as text input, in some very specific and rare circumstances?
