I just found that I have the same problem with add/remove's change/remove buttons disappearing. As much as I hate Norton, I don't how the original post turned into a Norton bashing session. I learned long ago that Trend Micro was the internet security solution. What I need to know now is how to fix the problem with the disappearance of my change/remove buttons in the add/remove program list. I have a sure fix for it and it's called Acronis True Image, but I would like to know what the basis of the problem is and fix it without using Acronis. I guess I'm just geeky like that. If anyone finds the solution to the real problem, please let me know. Thanks!
