This is sounding less like hassle now. I'm going to sit down (I hadn't thought of that til Russ's post). The ice-cream cone thing is a godsend - I reckon that'll make ie easier to maintain a consistent reasonable distance. I just hope it doesn't melt (sometimes visualisations take on a life of their own don't they?). Thanks again for all responses - I feel a happier and calmer person now. And much more in control.
