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

First it takes >10 seconds to load (for files <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.

    What chat transcript? From iChat? From Adium? Is there a standard for chat transcript files? Commented Jan 12, 2012 at 15:58

Might want to flush your various caches, specifically font caches - I like Cocktail and Lion Cache Cleaner for both.

Whenever you mess with .qlgenerator files, you should type qlmanage -r in the Terminal. This lets the whole QuickLook system know that you have gone around its back, and causes it to nuke its caches and re-initialize everything.

That may be the missing bit. I've known deleted .qlgenerator files to keep working until I did glmanage -r.

Before I discovered qlmanage -r, I tried emptying the trash after deleting the .qlgenerator file. This caused things to become unstable, and I had to re-boot!
