Mass shipments

Anyone else using mass shipments? We enter mass shipments and say ship all.
All the lines come up with the planned quantity and have the lines marked as
complete yes. If you hit enter after verifying each ship quantity it changes
the complete flag to no. Then when you say ok those lines that you didn't
change the quantity on are not created on the packing slip. Has anyone else
seen this happen? We are on version 3. Any thoughts would be great.

Thanks,

Jim Frice
