Summary: When I try to create a Multiple Choice (a non-intuitive process), I reliably crash the browser.
Steps:
  • Design a new Model
  • Give it a name (eg Alexx's Multiple Choice Test)
  • Click Add Property
  • Click Create a new Property instead
  • Click Optional
  • Select Multiple Choice
  • Type a Name in (eg "Choice")
  • Click Create
  • Watch your browser become unresponsive.
