title: Google Earth API - geplugin.exe consumes all available memory
body: <p>Good afternoon to all. I searched up and down the web and did not find a solution to this rather big problem.
  When I am running my app interfaced to Google Earth API, geplugin.exe comes up in the task manager and after a few user interactions with the Earth (zoom in/out, flyto a few points) all memory on their machine ends up being consumed by the geplugin. It unloads once they close my project but due to the business specs I can not keep on loading/unloading.
  My guess would be that Earth caches the images and does not release them.
  Anyone found a solution to this predicament?
  I am running Google Earth v6.2 on Windows 7 with tons of memory.
  Gratefully
  Ig.</p>
