I am not nonnox 15. But your answer was sent to me. Buddieus. I got 4 emails that were for ninnox 15. In the solved area above, that was the solution to a different problem. The problem for me is solved, but I don't remember how it was solved. I know I tried what was suggested here. But it didn't solve the problem. It happened with IE explorer a couple of times so it may have been some other problem. But it is gone. I now have another problem and will ask a new question.
