Frank,
I sympathize with you. These kinds of problems which appear to be random are almost impossible to track down. However, what you are describing is of a different class than what was happeing to me. I think I have finally dealt with my problem, but then again who knows. Thank goodness we all exist in the completely consistent world of Microsoft... <g>
A problem is a problem only as long as it has a possible solution. Lacking that, it becomes a FACT!
