its working as usual in our system .
you can check below thing if you havent done that already
if SCM is being used . you can check in the change and try out .. the other thing you can check is debuging the report from mingle ( to check if its the same object being called )
the other thing that i have experienced is the print format .. it behaves different in mingle and becs .. like print length 20 but print format %.30s
