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.
