Paolo, That was some good debugging. :] I'm constantly reminded of how much I need to learn about Java. Based on the information you gave me, I think I can patch the code.
I'm not sure why this problem is just now showing up. Maybe the other programms have some ideas. I will work on a fix today, and will post it to the list for others to review when complete.
