Question: VS 2005 Clearing Layer Problem

I am plotting a lot of points on a layer and then attempting to clear the layer to redraw new points to reuse the layer. I have found that attempting to use multiple layers and switching between them for the effect of a dynamic display causes falconview to become unresponsive (plotting 30-35000 points per layer). When i attempt to just reuse one layer by calling the layer.DeleteAllObjects method and reuse the layer for drawing, falconview memory usage still keeps climbing on the layer re-use like the layer wasn't fully cleared. Is there a problem with the DeleteAllObjects? method. Recreating the layer isn't feasible as it takes to long for smooth layer changes and multiple layers of massive point data almost locks up falconview. I am plotting changing radar data (weather patterns}

Environment

Language: C#
