I get the same error sometimes and I do not have lastpass installed. It seems to happen on my Nexus 7v1 running 4.2.2 after the screen has gone to sleep with nzb360 being the active window and one of my downloads in nzbget completes after the screen sleeps.
Thanks for this. I went into the lastpass app, edit app associations and checked "do not show fill window" for nzb360 and works like a charm again.

Thanks, love the app.

Heh, neither did I. I'll definitely try and include a fix for v8.0 due out this week.
