it actually happens in firefox as well. i'm suprised it doesn't do that for you.

i don't think firefox is stable on linux yet. see this post.

Weird. Unfortunately I don't have my linux box set up anymore so I can't check right now. (I use a mac with OS X and it's BSD backend to do everything I would use linux for). However, I am 78% done downloading Knoppix right now, so I'll test it out for you in Mozilla once I get it running.

There's so many different versions of so many different Netscape springoffs in use that I wouldn't be surprised if Google just did what the rest of the world does and that's ignore any of their code not working in some of those versions.
Just make it compliant to the latest standards and tough luck on any browser which doesn't implement those properly.
