Once loads had been generated, every time you went into Load Generation action or Loads and Forces action, the drawing of the building and loads in plan view would hang for many seconds, especially for complex buildings with a large number of loads. This also happened while you scrolled the view, selected walls, moved the window, edited loads, etc.
This has been corrected and the drawing of the loads has been accelerated by a factor ranging from a small amount to up to several thousand times, depending on the complexity of the building. The delay in drawing loads is now a fraction of a second and manageable.
