Just a quick heads-up, DP (david pretorius) has been testing and bug-finding on a new version of my ppmcentre utility, and it looks like it's now ready for other people to use, so if that's a tool that you're using in your processing work then have a look at the web page and grab the new version:

Support for Windows and Linux (and probably Mac and any other UNIX as well).
