that checkered blob is this:

it looks like Google Earth isn't saving the actual icon, just a link to it. Except the link leads to ALL the icons, not just one.
If you have Photoshop or something you could chop it up, but you'd lose the meaning then.
Any chance you could post up the individual icons (with their name) so those of us who add to My Places can re-ad the icon too?
Something is not right. This message is just to keep things from messing up down the road
