I'm having this bug on Construct 2, when I'm trying to preview it on browser.
If you look at the layout 2 of the file, you see spaces and answers. Using the drag and drop, every answer has it's space. Comparing the layout at the file and at the browser, you see that the spaces move to the right. I don't know if it is some dimension glitch or something else. Please, take a look at it.
(Sorry the bad english.)
