Identity Safe worked for years, now it's horrible

I have Norton 360 and have used Identity Safe to manage my passwords for several years, on IE and Chrome, without problem.   Now, every time I open the vault to find a password, I have to close it and re-open it to get it work again.   After I look up one password, it will always tell me that every site has the same password as the one I just checked.  If I close it and re-open it, it works.  But only once, and then I have to close it again.

After several years of happy use of IdentitySafe, I'm now finding lots of troubles that I didn't have previously.  Did something change?
