I'm creating pins in google earth. They are saving but I can't actually see them on the map (actually one appeared and then vanished). I've tried changing the image,size etc but with no luck. Googling for answer has been fruitless - one hint that it might actually linked to graphics capability of the laptop.
One thing to check (if it is linked to Graphics limitations) - go to Tools->Options and on the right side you will see the Graphics Mode option of OpenGL, DirectX and Use Safe Mode. Try safe mode first and if this seems to solve things, change the Graphics Mode. I have often run across across problems with GE not displaying properly and this will generally be the issue. Warning however, if you do change the graphics mode to a non compatible settings it can really screw up the display (won't start in some cases). If this happens google how to open GE in safe mode and fix. If you want to start more gradually, try reducing some of the other settings first (texture colors for example).
