Early this morning I tried to load some synths on a family member's laptop I'd borrowed. I discovered that the viewer never initialized, no matter what new synth I navigated to.
The Info, Share, and Favorite as well as the Play and Fullscreen icons would load against the default grey backdrop, but never anything else.
My typical practice is to simply use a Private Mode window so that I can sign into the site and comment without disturbing anyone else's cookies, but what was the case this morning was that in any Private Mode window in IE11, the site loaded and the viewer worked, however in a normal window it never loaded the viewer.
I tried hard refreshing various viewer pages repeatedly, disabling all add-ons, flushing the cache, and finally resetting all IE custom settings all to no avail.
