[MiKTeX] yap printing

[Peter R. <roq...@un...>]

Hi all:

Some time ago my YAP's printing behavior changed. When told 
to print pages from A to B in a dvi-file then it starts printing by A 
but forgets the order to stop at B and prints the whole file from A 
to End. If the file has some hundred pages this is inconvenient.

If I do the same from a pdf-file then there is no problem. Hence I 
suspect that something has gone wrong with YAP.

Question 1: What can I do to rectify this behavior?

Question 2: If nothing else helps, I would consider installing the 
whole of MiKTeX anew. Is it possible to install it over the 
existing, without de-installation? 

I am using MiKTeX since many years with satisfaction. Currently 
MikTeX 2.6.

Thanks in advance for your help.
