Richard,

It has been my experience in life, that when I run into a seemingly impossible problem, if I just step away from it for a short time a solution comes to mind. I can't tell you how many times I have left a difficult problem at work only to come in the next dayand have a quick and easy solution. It's funny how things work that way. So by all means take a break and it will come to you. Good luck and happy building

Bill
