Same issue was also in r79.3 , not sure about earlier versions.
In IE only (versions 7,8 and 9) games crash when there's a textbox in the game with the type 'Email'. The crash occurs when it tries to create the textbox, up to there there are no problems related to this textbox.
this happens on the code:
this.elem.type = ["text", "password", "email", "number", "tel", "url"][this.properties];
with the error code:
SCRIPT87: Invalid argument.
