Sorry, its a Monday morning, I was being kinda facetious, guess it didn't work very well :) I apologize. I know it must be annoying for you, its as much so for me when its something I can't just fix because its not reproducible. So, I feel your pain. Will try to restrain my Monday blues in the future.
