What is stranger, is that it only affects my 1 project. The Construct 2 templates open in different browsers no problem, just the project that I am currently working on does not seem to want to work...
I hope this doesn't mean I have to copy all the events and assets into a new clean project...
EDIT: Scratch that, the infinite runner template opens up only in Opera, and not in Internet Explorer... grr, what is going on..
