Support feedback: If a version of a file in CVS is an empty file, intelliJ can't handle it. If I want to compare the empty file version with another version in the "CVS - show history" function then intelliJ says "Cannot show differences: Revision x.xx does not exist in repository". Also the other functions "Compare with Local" and "Get" don't work: "Cannot load version: Revision x.xx does not exist in repository". In case of using text files that will be made empty often (like todo.txt, open_questions.txt) it is annoying.
