So at my request he sent me his original equirectangular tiff, which I rendered in Pano2VR. The fullscreen button still did not work. So now it's same project file, same equirectangular tiff, same skin, same...
Except...
He's using version 4 beta 2. I'm using Pano2Vr Pro 3.1.4 (latest version).
THAT's the difference!
I had read all the HTML5 docs, watched the related tutorial, etc. per Hopki's recommendation.
What I did not know is that those docs refer to... what? Version "3.x NOT"? V4 Beta? The HTML5 docs say nothing about fullscreen not working. None of the text in the HTML5 docs is redacted, which would indicate "this part is invalid, we're retracting it."
So I've blown a bunch of time chasing a capability I thought should work. I figured I was doing something wrong. It was bad enough that I had to eventually deduce that fullscreen has never worked on iThings (not even with v4 Beta). But I had no idea that HTML5 fullscreen does not work on any platform, in any browser, in the current stable release version of Pano2VR 3 Pro, despite instructions for fullscreen use appearing several times in the HTML5 docs.
I'm not happy right now.
