Multiple Choice: Able to "Check answer" even if no answer is selected
When you user multiple choice you can "check the answer" even if no answer is selcted by the user. That makes no sense.
If you choose to check without an answer given nothing happens and only the button "show solution" (if activated) appears. If you then click it it says "Answer required" (or similar) but you have no chance of giving an answer anymore and you are stuck with the error. There is something wrong with this process.
- You should definitely not be able to "check" an answer that has not been given.
