I too have had this problem. The only way I have
beenable to do it is before the workflow change be sure all
documentshave completed the workflow. Then delete the item form
theworkflow. If you deleted the documents while they are
inprocess within the workflow your sunk.
I hope they come up with a correction to this soon as it does
notallow for solutions to change over time and will get messy
asvaults get larger.
