Mine is not so bad, I just got a new computer and was trying to take some notes on people. After a couple days I realized I had put the same note on one person three times and it never saved.
Apparently with vista you have to have stars ran as an administrator or something, after messing around with it for a while they finally started saving.
I noticed that too, although I am not sure how long ago it happened, I probably had notes on most everyone that plays stud hi at the lower limits, I would bet that it happened with one of the last updates.
