OS X seems to be, uh, playing up? Yeah, weird. But over the last few days or so, applications haven't been starting properly, and Finder has been crashing out. Nothing which makes the machine unusable, but it's so very annoying. Basically, when I start an app (via Quicksilver, Finder, Dock, etc) it appears in the dock. Then the little black arrow fades in and out for up to 10-15 times before the application finally opens, sometimes crashing finder, or causing the taskbar to go all transparent and broken. It's just stunting my productivity somewhat. It may have coincided with OnyX being installed, but I haven't changed anything mission-critical (only the Dock position)... I'm at a loss. I've repaired permissions, that's all fine. I can't be bothered to install X again... suggestions?
