Some of my preliminary notes on V6 for those interested, particularly the performance - a couple of
other people have reported the same thing. I wonder if others are finding this too.
First though, a couple of embarassing problems:-
I ran the first installer to install the program, then the map installer took over and said it
couldn't find the program it had just installed. It was looking for the install location in the
wrong registry key.
Printing:- the drop-down list for orientation of the Print rectangle
is the wrong way round - select Portrait and it goes Landscape, select
Landscape and it goes Portrait.
But enough mirth, the important thing I found is the speed, or lack of it. Unlike V1.2, V6 is a .Net
application as has been mentioned already, and it therefore installs the .Net framework. This means
that V6 is compiled into an intermediate language MSIL and converted to native code dynamically,
which must impact performance for an intensive program like this.
Comparing it with Memory Map for the common operations of scrolling the map and zooming in and out,
it is very slow. MM always was noticeably faster, but is now much faster. Zooming in or out one
level is near instantaneous in MM, but an hourglass appears for *several seconds* in
V6. Scrolling the map in V6 is like dragging through treacle, with the map juddering and the
hourglass appearing if you drag a bit too fast. This was despite using 108Mb of memory on my system
(MM was using 8Mb).
I was careful to compare them at the same zoom level, since all the software packages scroll slower
as you zoom outwards. I don't know about the various features yet, but this really is a pain for the
basic operation of perusing maps.
Incidentally, if anyone was wondering if I could work the same magic with V6 and old maps as I did
for MM, forget it - the maps are in a different file structure.
