I'm seeing the same error with "Process ID 1776" as the culprit. However, I don't seem to have any process with that ID running on my mac.
Not sure how to dig further as to how to fix this.
Case-insensitive results are not working for me - I tried fudging with the 'c aspect of the query but to no avail. Can others relate if case-sensitive searches are working for them?
Thanks!
