I had checked for any evidence of Vista stupidity given past experience with having to look at the Virtual Store. But I've tried v. 1.4 and it works great!

Thank you so much for your incredible plugins. I'm using them for sci-fi mesh analysis and they are invaluable.

Vista and SketchUp 7.1.6860 . . .

Unzip of CoG plugin zip in the plugins folder resulted in a lot of overwrite requests (I just got your Manifold, too). I overwrote the older deBabelizer with the newer one.

Now on load a "Load Errors" window pops up, saying:

Error Loading File CofGravity.rb
undefined method `deBabelizer' for main:Object

And the plugin does not appear in the Plugin menu.

I don't know Ruby so I didn't actually poke at anything in the code, nor did I see anything obvious to me.

Just FYI.
