Do you know, that is what I love about these forums.

As always a potentially complex idea is actually quite simply sorted. Well done to Alan, I looked at the video at first and thought "how would I do that?" - then when Alan explained how to it was so obvious I nearly kicked myself.

It also goes to show that it doesn't matter how complex a piece of software is - ie pro titling software and so on - the simplest approach is usually the best.

Keep up the good work!
