G’day FLOOD, I’m pretty sure this was a data linking error in the database - it definitely wasn’t browser or software/windows related. I knew the username being presented by KPM at the browser wasn’t correct, so I went through the entries, located the ‘corrupt’ one and deleted it. Unfortunately this fixed the problem! I say unfortunately, because although I dumped a text file (which looked perfect BTW) I didn’t save a database backup - so I can’t replicate the error. Although I was able to go through and manually fix the issue I only had a handful of entries, if you had hundreds and didn’t know what username was for where this could be like finding the proverbial needle in the haystack…..especially if the same username was used for multiple URLs. Having plenty of database creation experience this glitch has raised an eyebrow, but although there isn’t a user-accessible data integrity check available (I asked) Tech Support were excellent and sent me back a great tip which is to enable tracing, so just knowing this feature has made the exercise worthwhile :-) https://support.kaspersky.com/14524
