Google Earth Crashes on Polygon Edit

Recently, Google Earth (4.3.7204.0836, Apr 24 2008) started crashing whenever I selected the "New Polygon" tool. Though the "New Polygon" dialog box would appear, I could not click on anything and the mouse icon, which is supposed to change to a cross hair (to place the polygon), would remain an arrow. Then, a crash report dialog would pop-up and I would be forced to close Google Earth. Quite frustrating. To fix this, I switched from using DirectX, which is the default, to OpenGL in the Tools->Options->3D View->Graphics Mode settings. I have heard that others have fixed this with enabling safe mode (located in the same settings dialog); however, this did not work for me. Apparently, there are some strange video card driver interactions occurring here.
