I want to thank everyone for contributing to this thread.  This explains so much of the "unexplained" that I 
experienced in the area of Layouts, and multiple instances. It make perfect sense now that the autosave
feature was pointed out to me.
 
I also appreciate everyone laying out their best practices since it well save a great many steps on my part and
others just starting out.

Best regards
Joe

I run 2 or 3 instances everyday, all are real time and auto trading.

1. turn off auto save like TJ have suggested;
2. each start with a blank startup database, then switch to its own
data base and stay there, never open the same database in different
AB instances at same time;
3. I don't save the real time feed data, but its safe to save I think;
4. the last closed instance has the final saying, so never save
anything except AFL code.

That's how I do it, have been trouble free.

Indeed! I strongly suggest that number of bars should be cumstomized
to each chart.

make the operation of a single installation using multiple instances
practiclal.

bars)... which was a pain...

reflecting a unique set of setting for a particular application (EOD,
Real Time etc). Is that nor correct?
