wincvs Graph

Hi ,
I got wincvs1.3.I have installed it and configured to local server(my Desktop).I have imported a cvs file from another repository successfully.I am able to check out the files but the check out files contain ,v files.What is wrong i am not able to get it.I am following the user guide of wincvs.
Secondly I Have copied a check out version of previous repository in my new check out folder.I have opened the wincvs.I am able to see the different versions of a file in a given module.
But notable to see the complete history of a module,instead of file.How can i do it.
Thirdly I went into the module.Selected all the files in a module.i am able to see the graph and the history.After that the selected file disappears from the wincvs window.what can be the possible reason.and it never appears even after shutting down the wincvs and restarting it.
Can you some how put a light on it ,what is wrong.
Thanks
