The stuttering scroll of the GC Tutor insert has been resolved. Apparently, the .animate( ) function is context sensitive and was triggering more functions than were necessary for the achievable task. You can see the correction in action by clicking first on https://tutor.grammarcaptive.com and then again on the phrase And, more … in the text that appears in the main panel of the Grammar Captive mainpage.
In addition, Grammar Captive’s new QR Box has proven to be very handy.
Today, while seated in a café, I asked a young Korean student to scan a copy of Grammar Captive’s QR Box that I had loaded as an item into iBooks on my SmartPhone. It took her directly to the GC Tutor webpage. When the webpage opened, she asked, “English tutor?”. I answered, “Yes” and thanked her for her help.
Without the QR Box things would not have been nearly as magical. Thank you, Chris Barnett, for the suggestion.
