If I create a numeric question, the default length of the answer is 0. This isn't a required field, so I could leave it at the 0 value. Once the question is created, it appears to offer you an answer box which is about 25 characters long, but when you try it out you can't actually enter any data into it (because it's zero length). Would it be better to have a larger default length, say 10 characters, which people could shorten? At least they would then always have an answer box which worked.
