TJ:  OK, thanks for the detailed explanation.  I have had only one chart
open and it has run fine (no lockups).
 
Of course, I noticed that I could have different time intervals in each
chart, which was more convenient that having one chart open and changing
both SYMBOL and TIME interval.  But....convenience with lockups is not
convenience at all.

Ken,
 
You need to understand that you are not opening TABS. You are opening
CHARTS. 
Each chart you open consumes computer resources.
And if you are opening lots of them and you work in real time it means that
all those extra
charts you have opened need to be refreshed when new data come in. 
 
And when you are working with QuoteTracker - yes it makes big difference
because
QuoteTracker link is HTTP (web based) which means that data are transmitted
in plain
web protocol which is slow. And if you do that for lots of symbols it may
lock up your machine.
 
So do not open extra charts/tabs just for fun. Especially when you work with
QT as data source.
 Open them only when you really need them.
There is no need to put all the stuff open all the time. It is definitely
*not* good idea to 
open extra charts just for different symbols/time frames when you can have
the same effect
by simply switching the symbol - consuming less resources.

Hmmm.  I really got into the tabs with different symbols, time periods
(intraday), etc.  Now, 1/2 hour in, the program is consistently locking up.
End Task, restart, lockup.  End Task, restart, lockup. Numerous times to not
seem a coincidence.  Have been running QT and RT AB for weeks and weeks now
without incident, including all day yesterday with latest version. Only
difference this morning was multiple window tabs open.
 
I had saved a bunch (6) tabs in the Default layout, and this last time, I
was able to call up another layout without tabs. So far, no lockup.
 
anyone else see this on intraday data?  I am feeding the data with
QuoteTracker if that makes a difference.
