Thanks Google!!!
You updated your Google Earth plugin this morning and now our app won't run anymore. I guess I could understand it if we were using some of the more esoteric features, but all we're doing is the very basics. A little easy javascript, and some WPF, no big deal. Oh, and while I'm at it, a BIG thank-you for providing no option to forego the forced upgrade (with no notice), and no ability to roll-back to the prior plugin that worked just fine.
So, we're dead in the water here -- until we figure out what you did, and work around it.
