In Finder you can preview files just by hitting space.

This function is broken since some days. Where to look at to repair this? Is there a setting in library, preferences or elsewhere?

Using: Snow Leopard, latest updates installed.

Does Command-Y work as shortcut in Finder? Does qlmanage -p path/to/file work in Terminal? – Daniel Beck Oct 1 '11 at 12:16
Command-Y does not work, qlmanage works. – Walter Jablonowski Oct 9 '11 at 1:00
Is the menu item File » Quick Look activated or deactivated when a file is selected in Finder? Is its keyboard shortcut Command-Y? Does Quick Look work in other applications, such as Mail (click an attachment once, then press Space)? – Daniel Beck Oct 9 '11 at 9:06
Well, it is strange... Shortly after the problem occurred it worked again, then the problem occurred again. At the moment it works... Maybe some kind of background service could be inactive some times? – Walter Jablonowski Oct 23 '11 at 14:21
Does it work for other user accounts on the same machine? – Daniel Beck Oct 23 '11 at 17:54
