This is a fun one. I've checked in a file with a date 4 years ago (was doing something else at the time that needed me to look at y2k). The file was first created in VSS in 2002. I cannot delete the instance I have created as VSS says that it doesn't exist and it doesn't appear in the history, however all history items of the file that do not have a version number now appear as if they are the version I have just checked in. My boss is going to kill me soon and I'd like to fix this before I die .... Any thoughts?
