Scott, this was sort of a problem that showed up with some the Xfades. Newer enhancnements in software have since made it easier for me to fix stuff like this, but before that, some just slipped through.
It is inherent inthe sample itself. You may want to try some declicking software on the sample itself, or try to edit it out.
I\'ll be honest, this was something that irked me, but was hard to catch all of them. There are more in fact, but most are so in audible that in most orchestrations they cant be heard. It was about time as well. I wanted to finish these things since I\'d promised to be done with them along time ago.
