Can you be more specific about what is going wrong? The zoom magnifier seems to work fine for me with or without twinx, but perhaps we just have different expectations of how it works. Could you perhaps provide screenshots?
I'm checking against SVN trunk. I didn't check against 0.90.1, since it would require installing an older version of numpy, and other dependency dances etc. But I'm happy to dig further once I have a better idea of what is going wrong for you.
