Preview Pane Causes Freezing All the time

[digband]

Anytime I have the preview pane on, both floating or attached, it just never seems to work - with the preview pane enabled when I land on simple files like PDF and MS Word docs, it will randomly force the XY app into not responding for a long time. This is really disappointing as I use preview all the time so I can see snippets of a file quickly without having to launch an app to open and scan it.
