My organization is working on an ArcEngine application that displays a GPS cursor for the user's current position. We are using custom-made GPS code since ESRI's is buggy in ArcGIS 10. Whenever the GPS cursor's position changes, the entire graphics layer redraws rather than just the cursor. This results in a map whose labels are constantly flashing as the cursor moves. We are pretty sure that the problem is caused by having the GPS cursor displaying on the same graphics layer as the labels and any other graphics, but we haven't had any luck finding a way to use multiple graphics layers.
Is there a way to have multiple graphics layers in ArcEngine 10?
