using merged sets and mame070u4 & clrmamepro 3.02.2. clrmamepro did not copy a number of files into the new dockman set.
(pe1, pe2, pe4, pe5)
Had to actually do it manually to get it to work.
Although missing it did not report an error on a full scan.
After correcting manually, full scan still reports no error.
Managed to repeat this problem again after deleting the sets.

chook.
