macromedia wouldn't recognize mozilla for flash/shockwave installs either.
i downloaded the players for both, installed it, had it select netscape and ie.. and then made sure to shut down the quick lauch and kill mozilla completely. reloaded, and it worked like a charm. but this method for me didn't seem to work w/ .97/8.
I've been using it as primary for a week now. just to get the feel. i like it, minus some formatting issues it seems to have.. seems a tad big slow sometimes tho.
