Hi Cetin,

My Source and BldMstr files are temporary, e.g. user may work on multiple registries at the same week. Each registry would create its own BldMstr and Source file. NextID would require to keep info about every file. It's not a big deal, of course, but I already implemented another solution, which is simpler and should be sufficient (I hope).
