I can't pinpoint if this is since the release, but I think it is - I am noticing increased problems with having two searches open at once in different tabs. You always have to be careful because you might run one and it gives you results from the other. But this morning I had two searches fuse together some criteria I was changing because I had them open at the same time, now the saved search that sends a daily report is totally jacked up. Annoying!
