When opening ConTeXt generated pdf's in Windows Vista, a message window pops
up saying something as (translated to english):

- title: preparation of document contents"
- message: "please wait while the contents of your document is being
prepared" + progress bar "page x of total pages"

This doesn't show up in Windows XP or Linux.

The embedded fonts are ttf fonts like arial/tahoma/verdana/times new roman,
...

Any idea to what that's related and how to disable it/have it run in the
background (if possible) because it slows access to reading the pdf.
