Eva, I just checked my app. If you are referring to question 8. Personal history in IMM5669 (version 12-2012) I did list travels every time I left the country. I remember writing an appendix because there wasn't enough space and looking at my old passport bcs I could't remember. I don't want to freak you out, I really don't know if they actually meant that you should list only when you left the country for more than 6 months, but I think you should check with more members.
Vienna didn't ask for updated schedule A from your husband? If you think it's a mistake you can send it with an explanation, they shouldn't make a problem out of it. Their questions are vague.
What I noticed the last time I applied for Tourist Visa is that they actually asked for travel history in the last 5 years, that was new, in the previous visas this wasn't a question.
