Tomasz,
Thank you for responding to this issue.
I understand the problem from the program point of view, but that is
no excuse for a genius like you doing this right from the user point
of view even if it requires more program smarts.
One way to solve this: When a study is selected, remember which study
is selected. If you click on the handle (or perhaps any part) of the
selected study then it remains the selected one --you do not change
selections to another study. So when the mouse is clicked on the
chart, check to see if it is on the previously selected study first
before looking at any other studies. If no study is currently
selected, then use the current AB method.
If the studies are only accessed by a linked list, then all the
studies would have to be checked up to the one previously selected one.
Another option is to re-link any selected study so that it becomes the
first (or last depending on program logic) one for checking.
You could also have a doubly linked list --one for the creation/draw
order, and one for the selection order.
Other programs have figured out how to do this, so I am sure you could
find a way to make it work right. It is just too important a UI
feature.
Best regards,
Dennis
