Sorry for delay with answer. About problem. Lets try to identify it.
1. Problem with blank line at the end in show differences now solved.
You can check this downloading new version of plug-in
2. Issues with status are not clear right now. Debug log really shows
that CVS reports that file status is "locally modified". So, could you
please try this:
a) Use the CVS NT server tested on our side
(

appropriate "Source control options" in PB.
d) Test all this with latest version of plug-in
