What might cause quicklook to 'freeze', as it were.
quicklook has gone south to some degree, some files are QL-able, other not, and we're speaking of the apple plug-in type (pdfs, txt, jpg, etc.)
Even whilst running the Topher 'fix', terminal hangs after either the qlmanage -r or qlmanage -r cache.
Cheers, and thanks in advance for any light your available time might hereby shed. :)
