Did you download Firefox ? What browser are you using?
I'm really not fond of it.
Anyway, in response to Chris_, I haven't found any button that makes the view compatible, as it did on the old Windows. But given that Microsoft issued Windows10 when it was only half done, before they worked out the bugs, I imagine in another couple of long updates or something, one will show up. That's what's been happening with other features.
I dunno why they issued Windows10 when it was only half operational. What bugs me about it is that I succumbed to their incessant constant entreaties, "UPDATE NOW! UPDATE NOW!," because I got tired of the stupid reminders always popping up.
In response to thundley4, no, I haven't downloaded Firefox yet, so as to have a browser. I'm really nervous about downloading stuff, although in this case I suspected I'd have to do it sooner or later. But then now today, presto! out of thin air, there's a new option on Windows10 that wasn't there yesterday. One can revert back to Internet Explorer.
I did, and the {quote} and other things on the "post reply" screen work.
In case anyone's curious, these new icons and thingamajigs, such as the "star," are nothing what they were on the old Windows.
