For a damn long time, BezelHUD, the Quicksilver interface plugin, was only compatible for the standart version of QS. Thanks to the rise of Snow Leopard, people got interested in more compatibility.
The awesome Ben Cochran took the time to make BezelHUD super compatible not only with Snow Leopard but also with Quicksilver b56a7 (the newest) from http://code.google.com/p/blacktree-alchemy/downloads/list
You can download the good old super new BezelHUD here: http://code.bencochran.com/bezelhud/
With the new version of OSX 10.6 the traditional version of Quicksilver from http://getqs.com becomes incompatible, especially my Interface Plugin BezelHUD.
I personally discontinued using QS in favor of the awesome Launchbar. There will be no update on BezelHUD from me.
Still I would love to see any developer hacking on BezelHUD to make it compatible again. Therefore the source is available at http://github.com/julius/bezelhud. Also my other interfaces Showcase and Silverflow are open sourced on my github-account.
UPDATE: Solution for BezelHUD
If anyone succeeds, please let me know.
