QuickLook doesn’t work with Chat transcript files Trying to use QuickLook for Chat transcript files isn’t working anymore on my machine. 

First it takes >10 seconds to load (for files &lt;20KB) - and then when it does finally load, it’s just an icon. I can’t actually read the chat.

Anybody else having this experience?

I’m not even quite sure what to try resetting! Deleting the QuickLook plists does not seem to have changed anything.
Might want to flush your various caches, specifically font caches - I like Cocktail and Lion Cache Cleaner for both.
