Kevin, apologies for that, but for once it's not all my fault. I sent the question out, along with a whole bunch of others, to someone who decided he didn't want to answer them, and since then I've forgotten to send them to someone else or answer them myself because they ended up in my 'questions sent out' folder and got overlooked.
Your post gives me the opportunity to say to everyone who has sent in questions that I deal with them as fast as I can. I've got loads of them on file and more coming in almost every day and I can't possibly answer them all myself, which means I'm very much depending on the good nature of the anglers I use to help me out.
I've got quite a number returned now and will be compiling another Problem Page feature hopefully this week.
So apologies to everyone who is waiting for an answer and I promise that every one will be answered asap.
