How to re-use markers in Subgurim GMap contol

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!

has anyone solved this problem? I suspect it can be solved in javascript but I have no J skills

Many thanks

OK I worked this oput - or rather worked out a workaround.

The subgurim control builds up a complete (huge) javascript command each time it refreshes. If you use a marker managr to plot the markers then set the markermaneger to empty - all the existing markers are removed and the memory gets released
