Question: I would like the ability to either turn off the zoom (rubber band) feature from, or preferably control the step size of the function, so it doesn't task so long. ie, we wish to u se the original CIT supplied function without rewriting it. 

You can control the zoom effect by the parameter [Trend]ZoomEffectSteps. This sets the number of steps the rubber zoom box will display between zooming the trend. A normal default value of 25 gives a nice effect, however it will depend on the speed of your computer and graphics card. If this parameter is not set Citect tries to calculate the value based on the performance of your CPU. In some cases this calculation may produce a slower zoom effect.
