Bug with lessons

The bar below appears even before the question is answered. It keeps showing the continue button.


September 1, 2013



What browser are you using?


Google Chrome Version 29.0.1547.62 (Fedora core 19 linux)


Do you know when this started happening? How often does it happen?


Well, it has happened to me a couple of times. Although, it happens randomly. I think it often happens when the network is unstable, and there are connectivity problems. The issue is that in that case I could and did continue the lesson till the end, yet it was confusing, as it allowed me to continue, although I had not answered the question.

The answer that appeared below, was from the previous question.


Ok, we will look into this.


I've had a similar experience with unstable network connections. I can refresh the page using Smooth Gestures 0.17.7 for Chromium (Version 28.0.1500.71 Ubuntu 13.04 (28.0.1500.71-0ubuntu1.13.04.1), but before it's refreshed, the "Continue"-button is there, and I can use it.

Iirc, this doesn't give me points or advance the green bar though.


Maybe, that's the formula for replicating the bug. Unstable connections + Linux operating systems = Bug with toolbar and continue button.


Something similar happens to me when there's an electricity cut (=Internet cut) showing me that my answer is correct whatever I write, and allowing me to continue answering the questions (or even leaving them blank), so if the Internet connection is back before finishing, I can complete the lesson 'successfully' i.e. it will be registered as learned.
