Hi Vlad,
Thanks for your comments. I might experiment using a timer control to get the desired type of behavior by refreshing the form. Not 100% sure the best way to go about it as yet, but I'll let you know if I come up with anything useful.
Be intersted to hear if you have any comment.
Many thanks,
Simon Swan
