Chrome all the way at home, though occasionally switch to Firefox or very rarely Safari if something's not working well in Chrome (I'm on a Mac). The images on the Chris CZ website are all distorted in Chrome for me.
I use Chrome with XP and the Chris CZ website is all wonky. It never occurred to me to try a different browser. I just wondered how all of you were buying stones from such a screwy website. LOL! I'll have to go check it out with IE or Firefox and see if it works!
