Another thing that's always annoyed me about PG2 was that by default the Update window stays open until you click the Close button. For the most part I don't care that it's checking for updates, or that it just downloaded a new version of my block-lists . . . that's what I expect it to do. Just do it already!
This is exceptionally annoying on startup, as the program will not actually start blocking anything until you dismiss the window.
It's trivial to fix this problem on your own, but I don't think you should need to fix this at all. And it annoys new users, those who are least likely to know how to resolve it, so I've decided to change the default to be to auto-close that window after a 10 second delay. This change will only affect new installations, when the "startup wizard" is first run (or if no peerblock.conf file is found), so if you already have things changed to some other settings you won't be affected at all.
An embarrassingly simple change, really, only two characters in length. Updated the configuration class's initialization-list, which is what holds the default config for if that setting isn't found in peerblock.conf (or of course if that .conf file doesn't exist). If the UpdateCountdown value is less than 0 the program will leave the Update window open until you click the Close button; otherwise that's the number of seconds we'll wait until the window closes.
