Random Reset of Studies?

I have noticed that several studies on multiple charts seem to experience resets and full recalculations for no apparent reason. Strangely, during these events, 'sc.LastCallToFunction' is set to true. From what the documentation says, this should only be the case if the study is being removed, or if the chart is closed, neither of which was the case here.

So, I was wondering if there are any other conditions under which this flag is set? It is my understanding that during a regular recalculation, this should not be the case, and with previous versions of SC, it definitely was not.

This is verified with versions 2009 and 2011.

Yes that is true and therefore this conclusion Is not accurate if these events as described above are not occurring:
. Strangely, during these events, 'sc.LastCallToFunction' is set to true.

In general we are not accepting that there is any problem at all in newer versions related to this. There is 0% possibility of this and we mean zero. It is nothing that we would even consider. It does not exist.

Apparently, clicking 'Ok' in the 'Studies' dialogue, even if you do not change the study in question (or any study), is considered a removal of the study. This is something your documentation should probably reflect. And I still don't think this has always been the case.

Certainly removing a study will cause 'sc.LastCallToFunction' to be true. That is verified. Studies that have been added, or previously added, and when you press OK or Apply in the Studies window, that does not cause sc.LastCallToFunction to be true. This is verified. Nothing has changed with this.

Maybe if you are doing something like linking Studies between charts, there could be behavior like you are saying but only for other linked charts but we would have to verify this. Whether this is the case or not, it has not changed.
