Either I'm confused or you...if I understand what you are saying, the comments that you put in your code (old or new) will always be there until you take them out. If you want to see comments in the VSS Show History option, you need to put them in the VSS Comments box when you check the object back in. Unless VSS has an option that I'm unaware of, it doesn't parse your object's code for comments and place them in the VSS comments. It would be nice if it did. If there is an option available to do this pls let me know!
