You're right, I've encountered the same issue in a project of mine (if you check for error in your browser
you'll see an error message talking about a DOM security issue with a slightly different message in FF/Chrome).
I came to the same conclusion that it was because the project wasn't completely loaded, and so you should make a loader screen
that will only give access to your menu once ALL datas are loaded.
Also, it's only experienced when the project is exported, not in preview.
Chrome and FF have the same behavior, this time IE is the one not complaining about anything and executing the game. Perhaps it's webGL related ?)Kyatric2013-03-26 01:24:55
