Weird, I use Google Maps all the time in Opera, probably almost daily, and never have problems. It used to be a bit slow, but that's changed with the new JIT engine in 10.6/10.7 alpha.
Ah, I've had such problems before. I fixed them by deleting all my preferences files, which I shouldn't really have to do. I'll try a clean install and see if it fixes it, thanks.
