Hi Trincey, thanks for sharing this. This is quite weird and I didn't encounter this bug yet, this kind of notification should pop-up only when you try to apply the code to the project or you ask to validate it.
You can try to use the exe instead of the index.html, and if the problem persist, use an older version of the tool (v1.0.1).
Please if you do so, let me know if the problem persist, meanwhile I will investigate on this issue! I'm off for the weekend, so I will likely to fix it at the beginning of the next week :)
