I'm hoping someone on EE has some experience of using the subgurim gMap control. In general this is a very good control but I'm experiencing a serious memory leak problem. I have an app that tracks vehicles, every minute it replots the vehicle curremt location. the problem is that the subgurim control does not offer a method to re-use existing markers so the system adds a whole set of new markers every minute. After 45mins it's using 1.5GB of memory!
