Yes, that does seem to be the case.
I suspect you are right - in the case of an app like a game, the app remembers
all of my history through all updates. I have often thought that you could
define a "workspace" that would keep the current session as a history, then

It looks as if you have the new j701 binary, but don't have the new data

Patrick,
You give 192.168.0.19:65001 which is exactly what the wiki page gives by
way of an example. This could be true on your system, but is unlikely, The

However. the other problems you and Joey report remains.

I'm away from home now, but I think what's happening is this:

It's rounded to the nearest float which is 100...0

You're right. Your

In your example only small fraction are used, and the methods discussed would

Hi Pascal,
I see the same behaviour in j806 as j805. Do you see something different?

in j806, .31 probably the j805 behaviour is

From what I've gathered so far is, that people
