Not working for me still - Opera, Win 10 using Straight Dope Light.
I suspect that is based on my laptop touchscreen. I am starting to think that is why I get the option of choosing between a desktop view and a mobile view of the forum. Swapping between the two does not give me mouseover. I might be showing up as a device that is assumed to not have a pointing device even when in desktop view. I may be seen as a tablet with the bigger screen that just wants the extra stuff onscreen that gets stripped in the mobile view.
If I am right that sounds more like a Discourse level “feature” in hardware recognition than a SD implementation of Discourse problem. A quick search does not yield anything to confirm or deny that guess.
Anyone else with a touchscreen and a pointing device that can report on their system’s behavior?
