We are facing a huge problem working with framesets. Assume you are working in a two frame-environment where one of the frames contains the navigation and the second frame contains content that depends on e.g. combobox selection in the navigation frame.
Now, whenever the combobox in the navigation frame changes its value, the content frame is recalculated. This is a big issue when the content is rule-based or contains a large dynarange because you will whave to wait until the recalculation is done in order to go on.
In our particular case a change of the navigation combobox chnages the value of a variable and the content of the content frame to some default screen by macro.
So the recalculation is simply unnecessary.
If the was a possibility to disable automatic recalculation of a certain frame on changing another, it would be a huge impact in performance.
