Ah. No children, then—that explains it.
I just noticed there's a new version of PBE, which I'll download now. I'm a bit curious what's changed, though... Have you considered including a change log for each of your apps? That stuff is usually interesting to your users...
Also, there doesn't seem to be anything in PBE's GUI to show you what version it is. Usually the version number is mentioned in the "About" window, so you might think about adding it there. (Of course you may have added it to the new version, which I haven't seen yet.)
