Hi Tom, the only time that I personally have seen cancel appear is when I or someone with the necessary security has cancelled a queue task or canceled a queue task that was in the same stream. on the queue can you scroll to the right and view the inforamation that you can link to?
Thanks for the reply Richard. However, it appears that the October CU for MS Project Pro 2007 was the culprit. This release fixed my out-of-sync issue, but caused the cancels to start. I had to back out. I have reopened the ticket and am working with MS on the resolution.
Hope this was helpful,
