I have been having a lot of problems with the Quicksilver Shelf. For a long time I couldn't even figure out how to get to it... even though I installed all the Plug-ins for the shelf function I could never find it (apple + space => s-h-e-l-f..) . It seemed to simply not exist.
Then one day I was just able to find it, so I set up a trigger for it. Now it appears without me triggering it any time I quit an application. Also, I can't access it by its normal trigger. I have to invoke the Quicksilver command screen first and then put in the trigger.
