The weird thing is I switched to Internet Explorer ONLY when I use Nutaku, and I don't these errors anymore. I was using FireFox before and it's so messed up. Parts of the screen would freeze while the rest still moves, Flash slows down, etc.

Anyway, I've been lucky with these RNGs, usually doesn't take more than 5 tries to get 3 medals on the difficult maps. And the easy ones usually only take 1-2. This Lillywood 3rd set is tricky with all the spiderweb obstacles.
