Turning off Ultrapeer looks like it may be the answer. Now when I check the Monitor window, requests are not flying by like they used to and maybe the message "Your client is a leaf-node shielded by an Ultrapeer. Hence you will see few or no searches in the monitor window" would be more appropriate now. I've opened Sharing for the colossal 24 files I have available again. Thanks for the help!
