Looking for a faster PDF viewer

[Paul Smith]

Dear All

The PDF viewer that I use together with LyX is GSview. Contrarily to the 
DVI viewer, GSview takes a few seconds to update the file shown when the 
file is updated by LyX. (With the DVI viewer, when I go to view the DVI 
file, the file is already updated on the viewer.) I would like to know 
whether there is some PDF viewer behaving as the DVI viewer regarding 
the issue above discussed.

Thank you a lot in advance!

Paul
