It turns out that the problem with using the search function is that I never actually have to ask the question myself as someone else has already answered it! I've also come to realise that there are a lot of threads here where questions have been answered and the person asking the question has vanished without thanking the person who answered it.

Basically, I'm just posting to say to all the people who've answered the questions I've not needed to ask; thank you!
