Thanks for reporting. This is one of a couple of known problems with
`View-quit'. I posted a tentative patch here
http://lists.gnu.org/archive/html/bug-gnu-emacs/2007-09/msg00154.html
and would be very glad if someone could try whether it helps to solve
this and related problems.

Please try the patch cited above. If you have any problems applying it
tell me immediately. It would be really important if someone helped me
testing this.

Note that `view-mode-exit' just executes something that has been put on
`view-return-to-alist' (maybe a long time) before. The source of all
problems is how the entry for `view-return-to-alist' is indirectly set
up when creating the "help window" in the first place.
I'm not sure what's causing the difference here. To find out you could
try to edebug `print-help-return-message' on both systems and look how
the value for `help-return-method' gets assigned. Maybe some option has
different initial values on your systems.
