So, do you think someone IRL changed it?

I have heard of filters one can activate that allows them to see everything that goes on - even in another user's set-up that is on the same computer.

I can well imagine that the "administrator" of that particular computer can see everything from everyone, including passwords??

If I have to assume that it was this IRL person, then it will mean a total collapse of a long-term relationship. That's why I need to be sure.

If it is just a glitch in PC's program, then that's one thing. I can deal with that. I can even deal with the fact that someone on the inside at PC is changing it (NOT that I am saying this is what's happening...), but if I approach this person, then the relationship dies right there and then, because, well, it speaks volumes about this person's psyche and where they stand with me. I doubt I would get the truth from them even if they did it. After all, not too many people are willing to come clean unless they are literally forced to.

I feel like I am being backed into a corner now.
