In a Table with SWT.VIRTUAL, when the user (under some
not-yet-fully-characterized situations) selects an item, I see this
call-stack, which I do not understand. What is the problem?

thanks,
Paul

My guess is because you are already in a replace (which probably marks
the viewer as busy) and you can't do another replace until the previous
is finished.
